Idea for dealing with spammers

[MichaelAgarkov]

What we can do to deal with spam bots:

• Approve every member who registered manually
• Require a link to a git account for registering (e.g. GitHub, Codeberg, Gitea, et cetera)
• Allow only whitelisted email services (e.g. @google.com, @outlook.com, et cetera)

Might also be a good idea to only let members who are at least "Multiple posting newcomers" to send links and include websites in forum profile.
