Hi Nariman163. Developing suspiciously fast doesn’t exactly make someone a multi-account, so unless you are relatively certain foul play is occurring I would recommend doing nothing.

However, if you are relatively certain then I would recommend filling out a bug report with as much detail as possible, for instance why you think they might be a multi-accounter. A bug report can be filed by clicking the cog icon in the bottom right hand corner of the screen, and then clicking on the bug icon and filling out the required fields.

Good luck in your conquests!
