So that explains it. I noticed it already when the delegation becomes available. I wondered what the gift box icon on steem-engine represents so I clicked it and it says delegate, I don't know what to enter for I haven't tried delegating before well aside from selling my vote in steemit and nothing happens so I just ignored it. Then later that night I noticed that there's +200 but honestly I never thought that it was a glitch or loophole. I sincerely though that someone sent it. Good thing it has already been addressed. Thanks for sharing this.
