I'm surprised by all the people here thinking your device is compromised. This is my experience with the Internet nowadays as well; a friend complained about it today also. The emptier the account the quicker you are banned as well (work accounts used every now and then during work hours, like twitter, are banned quicker than a private account that you login to regularly and share more things on). Old accounts are usually unaffected for me. Probably removing cookies/localStorage/etc. on a schedule doesn't help either. Every new account on a popular service where you can interact with others is like this. It's like everyone saw what google did to gmail, saw nobody cared about the collateral damage, and figured we can all fight spam without any human intervention. In the past we didn't have this problem because it was humans that looked at posts from new members. Innocent small Internet I guess.
