Why did strange things happened to my accounts?

Anonymous
I could be hacked but I don't know which one. It could be my computer, accounts or my phone. So it first happened few weeks ago that's my Facebook really got hacked. The email and phone number had changed but i managed to recover it because I found ways to undo actions.

Then weeks after, a strange youtube video appeared on my channel about piracy and a suspicious link but i deleted it ASAP and made an announcement to my subscribers that I never do it. So I changed my password and check for any unfamiliar login device but no other devices found.

Then the next day, my Facebook got disabled due to violations I've never done and it was a great offense so chances are I'll never get it back so i made a new one.

Then the next day, my Youtube videos got unlisted for no reason and it got me thinking that it got deleted. So I check again for any unfamiliar login devices but none. This is when I started to suspect that it could be my PC getting a malware because I do remember I downloaded something that Google warned me it's unsafe which crashed my computer one time just this month. So I moved to my laptop which is kinda brand new and untouched. So that is where I changed my password and turn things back to normal again.

After that I got a text message from my phone saying "send photos here at (a random gmail address)" I only opened the message but I never clicked the link.

Then just today, my instagram PFP was change to a girl (she's not even hot) then i got many follow requests after that. I removed it and saw many unfamiliar log in devices for the first time since the incidents and i removed them then change my Instagram password.

So I want to know which one is most likely to be hacked here it could be my emails or my devices but I'm not sure. All of my accounts have 2 way Authentications except for my Instagram which has the weakest security and im not active with that media anymore.
