This is going to sound really dumb, but are the posts in question the ones that don't seem to make sense, with weird wording combinations, from brand new members, or are they the ones that are trying to sell something? I never know if the ones that don't make sense are from a non-english speaking person, or a robot or what? Don't want to criticize anyone--I don't speak any other language, so I have no room to talk at all. Just wondering....
While I deplore the practice of spamming there is another way to look at it. At least it means that TEG has become popular enough that the spammers are going to the trouble to signup and leave their calling card. It's the price we pay for being popular.
