I can attest to Richgotya's lvl of playing around with us. He does it in good fun and humor.
I remember a few weeks ago doing some ridiculous mass spawn wave on my front lawn and told rich he should come join. His response was something in the line of "I got a surprise, let me know when do do it", something like that. Then when ready...like 20x20ft tall zomibe things riding bats in diamond armor popped up and distroyed us all...I think even rich died.
I think in total between all of us there we lost a combined 10k+ in MineCraft Dollars. Yet...none of us cared one bit...we all had a laugh and tore down everything in the end.
I've stalked people while invisible, think newb picked that up from me and a few others, and would screw with people in good fun. Rich does the same with Egging peoples houses...if anything, its funny and gets free food.
I'm sure if any major damage was done Rich would have been more then happy to reverse it for you if you requested. I mean, now you have Rich all hot and bothered....(no pun intended).
Also, in response to your issue with the Swiftness of the Admins...would you rather they wait a week before doing something, an hour? 20 mins? I'm sure that you would, more then likely, complain if they took their sweet time dealing with issues. I see no issue with someone getting banned right away/ jailed right away/ muted right away...You read the rules and I remember seeing some place that not knowing the rules was not acceptable as an excuse(not verbatim). Its called the Ban Hammer for a reason.
