For what it is worth ... I saw this sort of problem arising years ago and so I got myself a non-gmail(et al) account and that is the one i used here for Filezilla.
Although, I did use my gmail account in the first instance and was
surprised, like the 69% of you who so far agree (although that may change when I vote to "disagree").
I have seen boards, which use captcha and what-not to screen the new registrations, when left un-manned (for say a sudden personal emergency) go spam-tastic !
I say - if you are going to be giving away a great product like Filezilla for free and run a free support forum and let people discuss practically anything they want in an adult fashion -
then you screen out spammers in anyway you choose !
I mean .. how inconvenient is it for a user to get a new email account that the guys here at FZ do allow.

A few minutes (or even an hour or more) of your time to register an email account somewhere else is better than
countless,
thankless hours for a forum admin to be deleting spam.
And once you have an alternative account you can use it for other forums thus weakening google's market share;
maybe google(etc) will even try harder to control their own user registration if they see they are getting banned from forums like this on a regular basis.
My 2cents .. Disagree .. Die Spammers .. you are NOT welcome
