You're probably not going to get the response you want.
Such 'corruption' happens in all online games, whether they're huge scale games like MMoRPGs or small community servers like MCNR. I've seen multiple reports with similar accusations surrounding staff & certain clans which indicates there may be some truth to this, and there probably is. Clans have a LOT of influence and power on small community servers like this - they band together and all have their own interests in mind, after all.
You literally see this in-game. The most mouthy & toxic players are clan members. Why? Because they can. They've got backup and you're outnumbered bro.
You're mad asf you grinded multiple hours to get the houses you wanted, then had it taken away from you in a way you feel is unfair. I'd also feel mad. If it affects you and you aren't getting justice - quit or increase your sphere of influence like the clans have. Either way, that's not worth your time and effort, and nor is getting justice on a game.
The takeaway here? - online games are a waste of time. grinding and spending this many hours isn't playing the game. you're slaving away earning virtual $ with no real value, which can be taken from you at any time. also, it's not like playing MCNR for several hours straight is fun by any means, so like gambleaware say:
