How to Block Spam Mails?

Question

For my SaaS, a lot of fake accounts are created which seem to be automated bots from @mail.ru @bk.ru @list.ru etc domains.Now of course I could set up a manual block list or so, but I was wondering how you are doing it?Is there an existing service or at least a good block list that I can already use?Thanks![Edited for clarity]

Put your site behind cloudflare with geo and bot blocking should eliminate the vast majority of them.

This is not an answer to your question but existing sanctions should allow you to configure your application to reject any email addresses that use the .RU TLD. Not a long term fix but may buy you time to configure restrictions on the front end whichever direction you decide to go.

For clarity:Do you mean "I want to block incoming spam email to my email addresses" or "I operate an email mailing list and I want to block bots from joining the list" ?
