I say this in support of moderated sign-up, not as an argument against it:
I've signed up for at least two servers, possibly more, and never received the email that told me my sign-up had been accepted. The only way I knew was by trying to log on after a couple of days and seeing that it worked. If I'd been a newcomer, there's every chance I would have given up on Fedi without ever logging in.
The welcome email could do with changing so that it doesn't fall into Gmail's spam filter.
I know that spam filters change daily and that crafting a message to get through one filter can make it more likely to be caught by another. I appreciate that this is an annoying and fiddly problem, and I'm sorry to bring bad news. 
We had mice after cowboy builders left scaffolding up for more than a year.
We didn't pay for an exterminator: we bought half a dozen mixed traps, tied them securely to uprights, baited them with peanut butter, and emptied the traps twice a day. Within just a few days, all the mice were gone.
Mice spread disease and will gnaw through your possessions. I can't recommend ignoring them.
Best of luck, whatever you decide to do!
