Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex-edit at $00EEB2 in the ROM map, you can replay the level without a problem.
I was just now trying to get up to 3838 karma before I went off to play some Majora's Mask, and was getting the posts 100% of the time up until around 3600, where some guy that's fast as heck started to grab the posts within like a second. I mean, I thought I was fast, but this guy...
Finally reached my target karma after a duel of reflexes though!
Looks like I'm now a heroic crime fighter now. I've been eating eShroom Corp's spam for the past two hours (It's starting to get a little tiring getting rid of the spam; could someone pass me the TUMS?).
I just managed to get 15 or so eShroom Corp posts in a row (even mistyped twice and accidentally deleteforgreaterjusticed the wrong post one of those times, and still managed to get the eShroom Corp post afterward)... it seems coming in the middle of the night was a good idea.
