Personal parsers would've been a great option at launch. Now people already have other options, so it's not like you can keep that information from other players if they want to know. That option simply doesn't exist, so whether or not it would be a good option is irrelevant.
All a personal parser would do at this point is continue to keep console players more restricted than pc.
I don't know why this bears repeating, but allowing parsers wouldn't make harassment okay. If people are griefing you with a parser, just report them like you would now.
