Multiple Misskey Servers have just had a spam attack with many of their bots even messaging me personally. This may be a new spam wave going through the Fediverse, this time only Misskey servers being affected (to my knowledge)!
The translated message reads:
Nice to meet you! I'm Suzuki Tetsuya, also known as the criminal Midokuri (Noname)! My hobby is nuking various sites!
The Mastodon Update 4.3, which has just been released today, would automatically filter messages like these. Many users, already on alpha versions of that release, will probably not even realize this attack is going on! #FediBlock #SpamWave #Spam
