What’s with the recent spam here? - Lemdro.id

Google Translate says it’s Japanse. I’ve seen the same sort of post on a handful of other communities today as well (oldest going back about 17 hours)

Someone on mastodon said it was a group of Japanese spammers trying to sell their services. Not anything special, just a spam wave that’s hard to stop because they keep spamming from different instances.
Not that hard to stop if you use an automod of some sort.
I'm sure they'd appreciate a PR or something then, as mod tools here are reputed to really suck.
There are plenty available, as far as I know, most Automods are open source (including the one I’ve written and use).
Makes me wonder if they're linked with the spam accounts about changing flight tickets
