Actually there are times that we newly registered our account and suddenly we forgot our password,also their are times that we will forgot it because we have so many different accounts from the other websites especially if we didn't list it immediately on our notepads or any other safe place.

But since the issue is already there the best thing to do is to report it to the support since they will do a documentation about the lose password or email so by the time you register an account again they will not suspiciously think that you are doing something illegal on their platform.
