As much as I am for customization, there's a problem with CSS sheets. Text outlines can be used to bomb other players at little risk to the bomber.

Having a text outline of...
-dm-text-outline:90001px blue;
...froze my computer for ten seconds.

Having a text outline with one more zero...
-dm-text-outline:900001px blue;
...froze my computer for four minutes, and a friend for one minute.

Basically, if you have a good enough PC you can ride out the initial freezing time, save your profile, and then windows will- as long as you stay logged in- will not lag you again, even if you exit your profile and go back in. So you could walk into somewhere public with a really rad character sprite and clear out the area as everyone either reboots their PC or waits out minute-long lag.
