Honestly, trust levels are for people who are, well, regulars. If they don’t actually use the community much, they’re not regulars. They’re members, who occasionally use it. I have this with my forum; we’re seasonal. The only people who will ever really be TL3 are the ones who hang out year round. I’m okay with that. What use are the expanded features if they’re not visiting the site to read?
Anyway, if all your’e concerned about is nofollow, then maybe just turn off the option to add it?
