Chat bug, specific phrase blocked

Typing "got introduced to" in a number of variant forms, blocks the entire message from everyone else's sight. You can type "got introduced" and "introduced to" just fine, but "got introduced to" is blocked.

Blocked:
"got introduced to"
"got intrduced to"
"gotintroducedto"
"got-introducedto"

Not blocked:
"got introduced"
"introduced to"
"got intro to"
"got-introduced-to"
"gotintroduced-to"
"ot introduced to"
"got introduced t"

Seriously, what the heck?

Edit: to clarify why this is an issue, it's a completely innocuous phrase that someone could type in normal conversation and have NO IDEA AT ALL that their message wasn't delivered. We found this one entirely by accident. How many others like this might there be that we don't know about? How often is chat just... vanishing into the void?

Edit 2: this probably belongs in in-game bugs. I'll put it there instead.
