I used to remove only hitbursts in some extreme cases (when they're all the same colour, for example) a lot of time ago, but it's been a while since i decided not to remove anything from any map.
I can concur that some maps have disturbing elements (mostly epilepsy inducing SBs), but if i can't play with them i just flat-out delete the whole mapset and forget about it.
On the other hand, some maps should NEVER have SB/skins removed, such as Don't stop me Now, I Can Be Your Friend, and most of the fully storyboarded maps you can find here: viewtopic.php?f=20&t=28932&start=0
