Stop ruining the games for others, asshole. Why the **** do you play on a survival server when you're not interested in surviving/gathering materials? Go on a creative mode if you don't care about the core aspect of survival mode. You just **** it up for everyone else.

edit: For clarification I don't care if people want to ruin their gameplay experience in an offline game. But once you start bringing that **** to an online environment it's not cool. It starts to encroach on the experience of other players and that's a problem. It's not fun to go on a server to find all the mines stripped of anything valuable by xrayers, or having your hidden home exposed just because an X-rayer wants to show people how cool they are by having a modded client. It's even worse when servers or players try to implement some sort of trade/bargain system because here comes Mr. X-rayer with their 10 stacks of diamonds they obtained in a few minutes to rip off the players who worked for hours to obtain their supplies to trade with. Keep that **** offline or on servers that allow it. Or better yet, go on a creative server if you don't care about actually working to obtain supplies.

I'll be so ****ing happy when Minecraft implements a proper modding API and servers can regulate allowed mods and more importantly, block clients that don't match the proper MD5 hash from being allowed to connect to stop unofficial mods.
