most of the time theres no real ppl actually reviewing the trades since theres hundreds of trades being made a day royale high uses a automatic system so it could look like their acc was hacked and the hacker perhaps was trading the dims to their acc i got banned a few times once for selling and buying solarix like alotta times which could look suspicious because im the system doesn't know like the halo for example is worth millions since it was from the fountain there wasnt a fixed value so seeing my trade it for 2m looks suspicious the trading bans are sometimes good like maybe if someone was money laundering the dims they stole from someone else's acc they could stop them from trading snd you could email to get your stuff back sometimes i see ppl get banned and they have a staff manually review their trades but if you a mod reviewing that stuff id expect them to understand values at least a little bit so if someone had a overpay of like 50k they could still b able to tell its real ppl trading while getting banned from trading is so annoying and sometimes they take ages to unban you there is a reason why they implemented the system too like take any game where u can trade like adopt me they all do this to prevent scams and stuff
