A chest that tempts you to break the rules should not be there period. There is no reason for it to be there, therefore it should be removed.
In case you don't think so, hear out my edit here:
-------------------------------------------------------
After looking at the updated rule page on the forums, I got this, this "evidence" for block glitching to get to chests: "No block glitching, or using the block lag glitch to get out of the lobby, or break a block to climb/reach to a place you cannot get to by jumping/normal means."
This updated page, I swear to God barely touches the subject. If a noob comes on MCSG and reads that, I can guarantee that if they saw that chest on TSG2, they'd think it's okay to go for it because there's a chest there. I've been here for 8 months, read the rules countless times, and I still go for that chest just because it's there, and I'm able to get to it despite what the rule says, or actually what it barely says. If this is a problem, I want the damn rules to STATE that you CANNOT go into chests outside of the dome, or anything else for that matter. Once I see the rules say that, I'll stop. But I think it'd be much easier/convenient just to remove it completely so less people get kicked by it.
Also, if the chest WASN'T there, less people would be kicked for going into a chest that SHOULDN'T be there. It's like giving the mods an excuse to kick people just cause they can.
So therefore, I agree 100% with the OP.
