Why some Y!A geeks keep their Q & A activity is private?

Some people, myself included, ask personal questions and answer with personal-ish information. And I sure do not want people - especially if they happen to actually know me - looking through all that. And don't you wish sometimes you could delete embarrassing questions/answers? Also, the more popular you are, the more people look at your profile, that's why Top Contributors keep they Q&A activity private. I hope I helped. :)

We can easily cheat there by voting on our own answer and if some top member want's to hide there activity it may be due to that they do suspend our account but do we loss anything "NO" yahoo system is total weird i used to reach level 2 withing 2 to 3 days when i was lot active there just make few more account and vote for yourself and win 10 points if you have higher votes never mind as yahoo don't pay anybody i don't waste my time there also the answer we get there are not even 1% quality mostly there are many spammer too
