...anyways I'm getting very amusing spam invite requests now, by way of Russia, literally all from 5.188.210.0/24 and all putting ads for shitty websites in the comment.
And the account name ALWAYS ends with "mus".
Joemus
Lisamus
Paulmus
Tinamus
Benmus
...and so on-mus.
I'd block that IP range but it isn't enough volume to bother and it amuses me. Like, what's the point of this spammer? It's an absurdly low effort attempt on their part.
