thats another thing. no internet points, so no bots to farm them. upvotes really only indicate the quality of the post or comment that receives the upvotes. no way to use the total number of points to claim validity of your posts or to brag with them.
that being said, at one point we will need to figure out a way to identify and prevent bots that just post propaganda. while we wont have the problem of karmawhoring bots, they dont have the need to karmawhore and can try to spread their propaganda immediately.
i dont know, i dont think so (without a user asking them to?). i think it would be less trouble for them to just create new accounts on their own. same result, but nobody can claim that their deleted account was restored. i think restoring deleted accounts could lead to legal trouble?
