Today I received an unprecedented 123 reports from twit.social users who had been targeted by crypto spam. The spam accounts all were from mastodon.social.
I've suspended all the spammers that you reported - thank you! - but now we're going to have to keep an eye on mastodon.social. I know it's the default Masto instance, but it's up to them to prevent the mass creation of spamming accounts.
Otherwise I may have to block the instance.
@leo I’ve received a spam DM, too - for the first time on Mastodon. I couldn’t send the report due to an error message (“instance doesn’t exist”). I tried both - reporting it just to twit.social and additionally to an mastodon.social admin.
However blocking mastodon.social completely would be a twit-dealbreaker for me since too many of my friends are over there. Would be handy to be able to block 0-follower direct messages from people you don’t follow instead.
