Ini mods particular ones that edit system inis will get you banned. I've just spent at last 6 hours trying to figure out why the server's been crashing. It turns out a number of people have been running FL with different ini files. It seems that some of these cause the server to crash.
The same applies to cmp mods to try out a fancy new ship model.
Don't do it.
Ooooh, I wouldn't want to be those people when you find out who they are.
I reckon they have more than a slap on the wrist coming, that is unless they can give a reasonable explanation as to why they were running different ini files.
