In answer to your cross-posting fail, LJ:
From emiliglia via demon_faith:
The following line of code, though, doesn't just hide the repost boxes to you like the Greasemonkey code for Firefox going around does. It completely removes the option for everyone viewing your journal or community. I've done it for this comm as well as my personal journal.
1. Go to Journal > Journal Style
2. Go to Customize your theme
3. Go to Custom CSS
4. Copy and paste .b-repost-item {display:none} (make sure you're just getting the bolded text) into the Custom stylesheet
5. Save changes
Now not only can you not crosspost comments, but anyone viewing your account can't either. This doesn't get rid of the reposting option when you're making a new entry, but at least that one's easy to avoid.
