Working as intended?

Hey there's a player who keeps being listed as being in good standing Ashe user Ashen_Kitsune, who is frequently tagging people in the back while listed as clean. is this exploiting? This player has done this twice in less than 20 minutes, I thought Cautionary would kick in after what I'm seeing as 4-5 PKs that I could see. If it's the game, I'll just be careful, but with how little it takes to become cautionary this kind of seems like an exploit.

EDIT: sorry I listed only one of the potential exploiters, XXIMORTAL GOONXX or something like that is the other, they're crawling around in the PVE zone listed as clean with blue rabbit units with shottys, I just reviewed and they're still listed as clean even in retro

Last edit: Ok, so, the gankers never replied and I hung out all workday but the gist of it is this, looks like there's MANY ways to exploit this game's good/bad system and make it sneaky to reply to. That's... not really the kinda game I signed up for nor was advertised. I mean PVP is PVP and that's... good for the people who care about that, but for people who wanted to just play a damn game, that's kinda deal breaking. Maybe there will be a fix eventually but as is, working as intended or not, the experience is DOA unless fixed. I sometimes wish it wasn't so hard to be a mecha fan. But one can only beat ALLMIND so many times before your eyes bleed. Maybe there will be another mecha game in a bit.
