We do appreciate it when members let us know about obvious spam attempts via the forum. digitaldissent caught the latest one, schultzy has been a reliable sentry as well.
(There have been others, sorry if I don't mention you - it's like my Academy Award speech, and I'm nervous and only have so much time before the music comes up and cuts me off...)
The dead giveaways are usually the username (watergas, nokiaphones, 23092r8rkaf, etc.) and the fact that it's their first post.
There's actually a little icon you can click to "Report a post" in the column below the username. Every post has one:
Click that and we automatically get notified about the offending thread & user, with helpful links to deal with it.
So, thanks again, people, for helping to take out the trash, and keeping our playground clean!
