not sure how to contact a mod/message them, so I'll just put it here if that's okay. If not, feel free to remove it. I was followed by a "hot teacher" aka a bot. link: https://www.duolingo.com/HotTeacher697382
I have just began doing the French course with my young daughter. It is very poor that she is now getting emails in her name after only a few days with this "hot teacher" rubbish on it. Find a way to block it now please.
Yea, a few of us seem to be dealing with the same problem (same username except with a different number). :( In my case, it was to my teenager's account. I hope they find a way to sort it out.
