One thing I noticed is, the more subscribers I get, the more spam I get.

I turned on friend lock (which helps) but I still get spam.

For a programmer like you though, I don't think it will be too hard to fix, as all the spam messages have "sent to" and then lots and lots of names. So if you could get Toolbox to recognise spam messages, you could also get it to delete them!

Every day I have to go through 5-10 spam messages, with that feature though, I would only have to logon and the spam would be gone!
