Guild Wars 2

Good evening,

Recently i decided to go for my third legendary and that’s Bifrost.Been part of a World vs World oriented guild, i have to admit that i’m not a huge Dungeon runner and neither my guild colleagues are, so i opted for buying them Arah paths on daily basis so i can obtain the Gift of Zaithan.
Earlier today iv joined a party for Arah path 2 and after paying the fee, one party member said that Lupicus is not killed and it will report the seller for abuse and then he left.
Question: Am i susceptible for a ban if i still continued to remain in the party after the warning of been an exploited run?In my defense i have to add that i never checked if one run is ’’legit’’ or not, and that because i never knew the difference between a legit one and a non-legit one, and did my research only after this run ended.

I would honestly appreciate an ’’official’’ answer and if this case is bannable to at least get it faster.I honestly don’t feel like looking over my shoulder my entire gameplay time from now on.

Thanks in advance!
