As mentioned here I started a new board, so a couple weeks ago added an RSS feed to get some posts flowing. Within a few days a couple members signed up and were replying to these threads a couple times here and there. The new members seemed legit: No home page URL, no signature, no fake signature, American IP addy, nothing to make me think they were a spammer. I even replied to a couple posts. For some reason, I clicked back to a thread a couple days later and seen the posts were edited to include a fake signature with several links. This is the first time I've seen a spammer put in the effort to post and come back later to edit the post. Heck, the board is dead, I cannot even be ranking well for anything. I just set the edit time limit to 5 minutes and that should take care of it. Has anyone else come across this?
