What is the best way to contact Duolingo admins? My account seems to have been hacked. Two or three times, some kind of ads for pornographic web sites have showed up in my profile with a link to an external (.ru) site. Also names seem to be added to my 'Following' list without my having added them.
I have changed my password twice already, but this does not seem to have stopped the trouble.
Thanks in advance.
