OK, here's my quick list of reasons why an email address might get a lot of SPAM while others don't -- from my private and professional experience, not others' research:

Thanks - with my comments on those reasons:

GoSeigen wrote:-The hosting ISP has poor SPAM filtering or it is poorly configured by the user

I know nothing about this. How different are different ISPs, does anyone know? Has anyone ever attempted an analysis of this? In principle, if it is significant, a league table could be drawn up.

GoSeigen wrote:-The address has been published online

Definitely. This is a 'no brainer' and one way that would inevitably lead to SPAM. So much so that it can be taken as read.

GoSeigen wrote:-The address is vulnerable to dictionary attack (sales@domain.com, john@gmail.com)
-The address is on lists being circulated or sold, obtained from hacking, scraping or other means

Yes. But that only takes us back to the question: "Why are some on these lists and others apparently are not?"
My original email address was hosted by Yahoo! for a significant period.

GoSeigen wrote:-The address's owner was naive about SPAM: they replied to SPAM emails, tried clicking the unsubscribe link, failed to block inline images, left the preview function enabled in their email client etc

Yes. This would be my favoured reason wrt naive users. My rule with SPAM is never to do any of these things.

GoSeigen wrote:-The address is very old

Except that my old home email address originally dates from the Dot Com era and is still directing any incoming mail to my current email.

There is another aspect to this whole matter - a psychological angle. IMO it is a kind of general issue on the Internet: the problem of "representativeness"

Perhaps not receiving SPAM is actually the norm? But, on a BB where some people are complaining of SPAM, others looking on may feel it odd because they are not receiving SPAM. But they are not complaining of SPAM, because they are not receiving it, whereas those complaining are, because they are receiving SPAM!

Those receiving (and complaining of) SPAM now may not have been doing so last year and may not be doing so next year. Those not receiving (and complaining of) SPAM now may be doing so in the future, or may have been doing so in the past. e.g. Some years ago now, following a mistake in a mass emailing (SPAM?!) by a legitimate company, my then email account, up to then SPAM free, suffered SPAM for a couple of years - it came as no surprise that this was going to happen. But eventually (whether due to my actions or not!) things returned to 'normal' i.e. No SPAM.

My general point here - disputed by some - is that SPAM email etc. is clearly in general NOT "inevitable", not something we "just have to put up with". From my own direct experience over many years (1990s onwards), not receiving email/phone SPAM is the norm.

If other people disagree with this (direct experience) then AFAIAC it's up to them to explain why this is so in their case. Simply explaining how peoples' email addresses can be found out is not ultimately a full explanation.

A luxury hotel chain in Thailand is reporting a data breach thanks to a notorious group of cybercriminals who have been behind a spate of attacks in recent weeks.

Thirayuth Chirathivat, CEO of Centara Hotels & Resorts, said in a statement that on October 14, they were "made aware" of a cyberattack on the hotel chain's network.

An investigation confirmed that cyber attackers had in fact breached their system and accessed the data of some customers. The data accessed includes names, booking information, phone numbers, email addresses, home addresses and photos of IDs.


A mate was working in Edinburgh earlier in the week, got asked for his mobile number in a couple of restaurants - started receiving scam calls purporting to be from Edinburgh Sheriffs court a day later...

Why was he asked for his mobile number by the restaurants?

This scam has been so prevalent lately that the Edinburgh Sheriffs Court website has a warning about it on their home page.

Probably just coincidence wrt to working in Edinburgh and giving number to restaurants (presumably for Track and Trace).

I presume T&T.

Edinburgh is a big tourism city - the biggest in the UK outside of London revenue wise, therefore it will have a good network of underworld affiliations.

A bigger worry is if the scammers did it via leaked phone or network location data - which is now a reality rather than a theoretical risk.

I spent ten years travelling internationally for work and had quite a few ploys to try and prevent data leakage /hotel room thefts et al.

In room safes have master codes that can leak, I never use them.

If the front desk insist on keeping your passport or other ID - check in to your room then immediately go downstairs and get it back saying you need to visit a Bureau de Change. Cloned passports get a good price.

Hard shell suitcases /laptop cases (e.g Samsonite) with decent bike locks (the D type with a guarantee) to secure to bed frames when not in the room.

Cash - tape it behind the wardobe.
(But don't forget like one tour manager I know, who left an entire £30K tour float in a Paris hotel room and didn't realise until he got back to the UK.
Luckily it was still there when he got back a day later and his employers at the time were none the wiser...)

...Interesting. Just occurred to me: someone I know has been complaining for some while of receiving lots of wrong number calls to his mobile (rather than scam calls). Mostly from Scotland. He has no idea why.

I received a call from a number in Arbroath yesterday, I was driving so didn't answer, they didn't leave a message. I live in southern England and don't know anyone there so didn't call them back.
