Nevermind, turns out they trade ban for xtrade despite it not being in their hidden rules (wiki rules)
Probably 20+ people who sold me idlescape are since banned for "being my alts" lmao.
Even after clarifying with their staff that they weren't my alts, staff unbanned some of the names I knew about, but kept the rest of the xtraders banned.
They assume that "they will appeal if they did nothing wrong", basically on par with putting people in jail because they would lawyer up if they did nothing wrong. Pathetic administration.
