Okay, so I had Humphreythewolf, an e621 user blacklisted. I haven't had any problems, really, until now. Every time I blacklist him, I get the messages "BL," which stands for "blacklist," then I get, "user:humphreythewolf." I only get these messages when he is in my blacklist. That means that every time I load a new page, I get the messages. Since I removed it, I haven't gotten the messages. Does this mean my account has been hacked?
