what's the point of all these random accounts creation? seems like a automated process. would it be to upload illegal stuff?

I've set registration to Require application again, don't like this bots creating accounts.
Also I'm running into email limitations. Using the Sendgrid Free plan of 100 emails per day, but if a couple of member have email notification on, I'm reaching that 100 very quickly. How do others handle the high email traffic ?
Try enabling the captcha in your instance settings, it might help a bit as well!
While looking for a way to enable captchas I found out that they will remove that feature from lemmy: https://github.com/LemmyNet/lemmy/issues/2922
Wouldn’t it help to force registrations solve an expensive proof of work on the client side?
That would probably only slow them down. And since their main goal is to create a ton of working accounts, speed is probably not that important to them. On my own instance the bot-registrations stopped immediately after I enabled the required application.
Captchas are mostly useless nowadays against any well designed bot. The only ones that sort of work are those ridiculously hard ones like several page math problems. And at that point a large portion of people can't solve it either.
They also tend to be full of trackers and are terrible for privacy. Plus they're used to train corporate AIs.
It can help temporarily, because a lot of bots don't bother with captcha solvers, but all the spammers need to do is include a pre-made solver library and the bots are back.
