We've recently seen some very clever little trickeroos employed by spammers..
One particularly clever tricky goes like this:
- They make a post that seems harmless enough (no spamlinks, no bad signature, etc.)
- Then a month later and after the post is quiet without new replies, they come back and either edit the post or add a spam signature to their profile (which shows up on ALL of their posts even ones they made a long time ago).
The reason this is so sneaky is that regular forum members wont ever look at the old threads/posts and so won't notice the change and spam addition to the thread. But anyone new visiting the forum thread due to a search will see it.
SO.. i've added some new alerts that send us mods emails whenever there is a suspicious looking post or profile/signature modification, so we can have a look if it seems spammy.
Anyway -- let me know if i broke anything in the process..
