Question

would deleting your only comment and reposting constantly get you +10 points?

Answer 1

It works, got an extra 100 and leveled up this way.

Answer 2

It is currently theoretically possible to game the system this way, yes.

Answer 3

I just put it into practice.

Answer 4

Thanks for bringing this up, we know about this issue, and want to fix it soon.

The thing is, beyond a certain level, the amount of XP required to level up scales so much that you have to delete and repost it too many times to get a level.
