Ethical hackers (or non ethical) of reddit may I ask for assistance? Someone tried to hack my Facebook two or three weeks ago and at the same time my reddit account got flagged as having suspicious activities. The hacker managed to access my reddit and even commented and joined subrediits. I managed to change my passwords on both apps but I'm afraid the hacker might have backdoor access and might try again. What should I do to prevent it from happening again.

Ps. I have 3 devices, phone, a PC and a laptop. Please don't try and take advantage of me, I just need some advice.
