I'm gonna say no. While it would be nice and convenient, you never know what the original icon maker might prefer, you know?

Some of them do want to cultivate followings and have people friend them and stuff so while I personally am fine with my icons being spread all over, some people might prefer to control where they post them and I think it's best to respect that.

That said, you could always point them towards the comm to see if they'd want to post the icon sets here themselves since it's pretty easy since they're allowed to just link to them.
