First time to see my Hive Resource Credit and Downvote power dropped!

I’m not comfortable seeing my resource credit and downvote power dropped when I know that I’ve not downvoted anyone.

Yes, I’m following some curating trails but I’m surprised to see my resource credit dropped.

Ordinary, my resource credit can only dropped if I’ve done massive and numerous activities; commenting, transfers, posting, voting and so on.

I’ve also checked my curation trails to see where I joined in downvoting someone or engaged in such numerous activities that could warrant my resource credit to drop.

I’m worried about all these. I’m worried about Hive security.
