To reduce the amount of scammers trying to message you from being subscribed to any crypto sub including r/cryptocurrency...

I often get private messages from scammers chancing their luck. But I saw some great advice posted by u/latteisnotcoffee - Go to: https://new.reddit.com/settings/messaging

Turn chat requests to either 'Nobody' or 'Accounts' older than 30 days and you'll be able to avoid some scammers contacting you. Stay safe out there.
