My problem with the filter is it blocks any and all numbers you throw at it, making it extremely hard to actually receive any meaningful feedback. i.e. player says they were at a specific coordinate in-game, and the filter blocks it. That’s not directly aimed at the feedback system, but it is a problem present in milsims.
If the filter only blocked cursewords, and things that look to be personally identifiable information, then I’d have no problem of using such a feature. However the filter sometimes goes haywire and blocks everything you’re trying to say, even very simple phrases that aren’t even remotely close to inappropriate.
I am pretty sure the lack of a filter in a feedback system that will never be shown to another player, will go against the TOS. Haven’t heard anything from Staff, so I’m not entirely sure. The filter is broken for the most part however.
