Steam username account warning.

Hello there. 

Back in October, I received a warning because of my steam username. Understandably, it did contain a profanity even though the word I used was on a "lighter" scale of it, not even considered a profanity by most people these days. But it's whatever, ToS is a ToS, so I changed my username to remove the word but keep the spirit of a quote I'm using as a username (original was "keep drilling you piece of s**t", asterisks just in case I'll get a forum ban for it too, but it's a somewhat iconic line by one of the characters in PAYDAY 2. Ended up changing it to "keep drilling you piece of shirt").

So yeah, I've been playing for 8 months pretty much every day since then without any issues, but yesterday I've been given another warning for the same reason. Idk and Idc whether it has legitimately offended someone or it was a revenge report, both are possible given the recent influx of new and trial players. What I really want to know is how much I'd have to change my name while keeping the original quote from payday2 recognizable, considering rather vague wording in ToS on what can be flagged as profanity by whoever/whatever reviews reports initially. Do I have to change it completely because quote itself implies profanity? Will it be enough to change offending word to [redacted]? I'm at a loss here
