I have mixed emotions about this change.
Honestly the team got kind of lazy when attempting to fix this spam issue.
I'll copy-paste a post I made on reddit:
This is good progress but for the overall appearance of the game to new players, it's bad.
They REALLY need to implement a server-sided solution to block spam in the first place.
Imagine being a new player and everyone has you filtered, people are filtering you in the COOP MMO BULLET HELL SHOOTER, very misleading.
A 10 word block-list does not equate to a server sided solution to spam.
