Anonymous signup - eviltoast

I tried a bunch of ways to signup anon; first I tried to use maildrop.cc but the email conform never came through but there was no error message saying that maildrop is not accepted.

I also tried a few other ways, but eventually used onionmail.

My username comes from fantasy name generator; and all was done via the tor browser, running on Linux.

What is the opinion of the crowd on onionmail and torbrowser in general?
