I've noticed a number of people on SO who:
- Ask a question (often very basic), and then
- Answer their own question, and then
- Accept that answer as correct.
Thereby giving themselves 15 points. Doing this once or twice might not be a big deal, but I've see users where over half of the answers chosen as "correct" are their own. Tom Tom is the one I am most recently aware of, but there are others. This is ridiculous!
Surely this would be a trivial thing to check for and then ban/limit/something the offenders. I don't give a damn about points, but I do mind wasting my time on these (and related) sorts of people.
I know the subject of Help Vampires, Rep Mongers, etc. has been beaten to death, and I know there are some people here who think there is no such thing as a "stupid question," but it's getting to the point where I am spending more and more time looking for a question that is a) interesting, b) worth the effort to answer it. And as a result I am less likely to even return to SO to look for something where I can be helpful.
At some point SO itself may simply cease to be worth the effort ... and that would be unfortunate.
