I updated my post a moment ago and only now I read your comment @reggaemuffin
ps. the biggest problem I see is the fact, that I couldn't find any informations on dlease.io which could point me in right direction and help me figure out why does my account upvote theirs.
Also in current days people lose their accounts on different platforms almost on daily basis. Hacks are everywhere. Even giants like Binance has been very lately a victim.
And now, just imagine waking up in the morning and learning that 3rd party (of which I didn't know and couldn't figure out) had an access to my account and using it to upvote some content.
That is some scary shit.
ps.2.
Thank for that link.
Cheers, Piotr
This is because the upvotes are not related to dlease.io and the information is under to upvoted post itself.
I think it is impossible to provide enough information that someone in a panic state of "I AM HACKED!!!!!11eleven" will be able to find out why it happened.
