That's crouch-glitching.
i am new in this server + I did wall glitch by mistake ban me next time i won't do it again.
I hate when players are starting to lie. You're not new, and if I'm right I had warned you once to not c-glitch. About the Flamethrower wall-glitch I can't say much, because I believe Subzero wasn't aware of that he was wall-glitching and that Bart was taking any damage as Subzero was throwing flame towards the entrance of the "building".
Temporarily banned for 3 days, thanks for reporting.
@Mad_K!LL3R , please refrain from posting in here if you've nothing to do with the report.
