Self-upvote XP is gone

Following @Westicles abuse of the self-upvote feature to get a large amount of XP, we’ve decided to remove the XP granted by self-upvotes. Others have abused it before, but not at this scale.

We were aware of this flaw in the XP system but since its impact has always been minor, we thought our time was better used on other projects. Anyway, all XP granted through self-upvotes have now been removed.

These kind of repeated abuses/disruptions of the community well-being will now be more severely condemned.
