Might anyone be angry with you?? I am not familiar with these sites, but if someone either can log in as you (i.e., knows your username and password) or if someone has penetrated your computer and is manipulating the sites in the background, then this kind of stuff could happen. If you haven't already, I suggest changing your account passwords ASAP, double-checking your account recovery email address (and personal questions, if applicable), logging out, and logging back in again. Then I would change the password on the email account you use for account recovery, just in case someone has that as well. I also suggest logging out of all these services in your browser using the link provided by the site so that someone with remote access to your computer wouldn't be able to simply open a browser into your last session. And turn off any automatic password filling for these accounts. Check your computer for malware. Our support article suggests free scanning/cleaning tools that take considerable time to run. If they finish question and especially if they demand a payment, you might have a serious infection. Please consult the specialized forums listed in the article in that case.
