Naming no names...
I recently discovered that another user on one of the Stack Exchanges I frequent is a person I used to know in real life, who is still trying to chase after me despite my making it very clear that I don't want their company. This person has joined SE only in order to stalk me. So far they've posted one answer (to a question I'd also answered) and one question (which I believe was set in order to entrap me - the topic is a joke the two of us used to share IRL back when I used to spend time with this person), and participated in chat speaking almost exclusively to me.
When I joined SE, I tried hard to ensure my anonymity, mainly because I feared this person might try to stalk me. I no longer feel quite comfortable using SE, knowing that this user is following me around and watching what I do. But as far as I know, they haven't broken any SE rules.
Is there anything that can be done by SE administration? Are people allowed to join SE purely to stalk other people? Or do I just have to deal with it?
