Sigvertisements have never bothered me, I think it's cool that people can make a little money for something small and easy. There can be confusion about what is a sig ad, and what is a forum ad. This could make theymos's job harder if something illegal/viral is advertised, but as long as those are deleted I don't see a problem.
Maybe provide your own bitcoin forum that doesn't allow advertisements? I hear that reddit is popular.
I won't leave a previously good forum and "provide" another one just because somebody tries to destroy the original one. The vandals should be eliminated, not us.
There is nothing wrong with sig ads IMO.
There is. OP has described it quite well.
But you couldn't have writen anything different than you did, no surprise. :-(
You should respect where bitcoin economy currently is. For now we are in casino stage. Hopefully we'll go further and we'll establish higher levels of system.
That's right. It is helping members with little BTC to earn more, and helping the economy.
The most important point of the OP is that the sigvertisers make their posts as frequent as possible even when they have nothing important to say, diluting the forum contents that way. And I personally hate wading through a junk contents just for some advertises' pleasure.
