I'd like to see iHub develop a filter, like Raging Bull has.
That way, they could disallow any string they want, such as "lebed". There are no legitimate words in the English language that contain that five-letter sequence, so there'd be no downside to disallowing that string. Any post that contains "lebed", doesn't appear.
That might help with the spamming a little bit.
Actually, though, spamming is not a problem on iHub. What spam there is, is so seldom, it's not a hassle IMO. The present system seems to be working fine from my standpoint.
