I wasn't in on the other part of this conversation, but this is a wiki site. So, editing, in general, if you're not on the Trusted List is very much OK.
The problem comes in when people start editing without providing sources for their information or they start changing the layout someone has worked hard to establish.
If you see a profile that has had a lot of work done on it, it's always best to leave any information you have to share in a Public Comment or send a message to the Profile Manager; however, if you are coming in to do GEDCOM clean up, fix obvious errors like typos, obviously bad dates, etc., there's no need to be on a Trusted List to do that on an Open profile.
I'm probably a little off topic here, but if someone else comes along and sees your question without understanding the context, I want them to understand that general clean up is welcome. :-)
