I've - previously - noticed that I can like, reply to, mention, even upvote myself...
Mentioning doesn't send me a notification, while upvoting doesn't change my score.
It wasn't an issue till I saw this:
I thought that maybe that could be misused.
If I upvoted all my answers so that they had a big no. of upvotes, I'm by that misusing the upvote feature.
The same with liking; the post with the most likes is likely to be the best post, especially as no one checks who liked who.
Mentioning & replying aren't an issue, but they are just meaningless if I did that to myself.
