Should this person be banned?

No, not banned. The asker should have the ability to revoke the 2 points to the person answering the question if it is someone trying to be intentionally stupid with their answer.

But the same can be said of askers who get some incredibly well thought out answers/responses to their questions, only to allow it to go to a vote. The voters seem to vote for the most ridiculous answer making it a waste of time for those who truly answer in an intelligent fashion.

That alone is causing me to not answer questions as frequently as when I started out. Why bother taking the time if the asker won't do the same to decide which response is genuinely the best?

Blatant advertising should be banned, and I think they do. It's ok to give site addresses in response to relevant questions.

Sill answers, and questions are a part of this site and are harmless. There are people of all ages on here.

I don't know about you, but I've had quite a few chuckles looking at some of the answers. You normally always get at least one good answer to your questions.

A warning with suspension and then banned. The problem is that as soon as they are suspended, they will just open a new account. It is next to impossible to moderate an open forum.

that is a conspiracy orchestrated through the Bush administration to positioned crackpots out in the open, to furnish us suggestions of what now to not believe. 9/eleven became a cover up!! Periodic table!! Sheeple human beings!! BANG!! BANG!! BANG!! (video reveal now has indentation of my head) I mean it really is someone with a distinct personality ailment, yet each and each personality is form of a member of a help team that convenience one yet another. who's more desirable helpful to believe you than your self?

That's trouble here, even though you'll suspend him, he can be back creating another Yahoo ID, within seconds.

The only way to handle this problem is to tolerate him. What else?

Are you the Yahoo Police? Yahoo Homeland Security?

Just report the spammer for every spam post you see. They'll ban him eventually.

I think Yahoo team should reduce his points and advice him, and if don't change his way of act, then banner him...

Who really gives a rat's behind? Just ignore it instead of whining about it.

At least suspended

Hey... let's just cut his fingers off and thay way he can't use his keyboard... and we can even cut something else off and he can't screw up any more postings.
