I have a fair bit of experience with word and phrase filtering - in fact I developed my code on phpBBS.
Some things that may be obvious but I'll offer them anyway
1. Spamming is very easy to do with various robots
2. Intelligent bots now exist to defeat captchas (I hate those things anyway) and appear to be entirely human - there are many more of these
than you might imagine. They are everywhere.
3. Most spamming is just malicious and the spammer will put much
effort into bypassing security
4. Some spamming is now done "live" by low paid teams in asia
5. NEVER EVER telephone or write - you have no idea if the number given has any connection to the message and could end up with legal problems yourself
6. When filtering try to look for patterns - same domains - same times of postings - (if you want to be clever) same message paths - same phrases same punctuations etc. Spamming always has such patterns.
7. Filter on phrases as well as words - include missspellings plurals etc
8. collect a database of the full details of the spam message - (dont just delete them) you can use that to identify patterns and as evidence should things "get nasty"
9. If you can demonstrate financial loss (labour costs etc) you can use the
small claims court. Even if you lost the spammer will think very hard before repeating the actions. If you win you can get costs and its not that expensive anyway.
10. There is at least one very big blacklist circulating but access to it
is by invitation but you could start your own. I'd suggest you do it quietly though. Some see the likes as a red flag to a bull.
11. Given the proliferation of these (removed by spam filter) messages you might be able to persuade your local bobby that it constitutes harrasment.
12. Any genuine business using spam will stop as soon as they get a few complaints or if you send a polite email asking to be removed from their lists (keep copies!) - so on going spamming is either idiots or malicious attempts to damage you.
13 - No - a business model based on spam has never worked. A few people
are stupid enough to fall for any con trick and thats why they do it - money can be made but spamming never supports or maintains any business that I've ever heard of.
14. Get in the habit of telling suppliers you will not accept emails without a valid return address. The practice of:
noreply@example.com is your biggest enemy.
(and EXPECT them to read any replies you do send and tell them so)
And finally - be very careful of clicking the "remove" option. It is usually used to find out if anyone is there to fine tune responses.
