This will work for a few minutes. Then the SPAMmer will change the format on you. The contest between a forum admin and the junk-mailer is a never ending arms race. Been there, done that, and the t-shirt was too small.
Thanks for your input Mr.Bear ;)
Well what it amounts to so far is ....telephone numbers, always 7 or more digits. This would atleast stop any NEW posts if user post count is less that 5 or 10 posts and contain 7 or more digits. This proposal would stop him in his tracks and atleast the spammer/s wont be able to spam new posts with telephone numbers.
The spammer always starts with a few special characters, then followed by a word usually, then a string of digits that is always 7 or more in length then some more words, usually jumble though. This is the only format spam we get lol, and it ALWAYS contains telephone numbers.
