Crawl error vs RSS feed content

[tishimself]

Hi,

I have a BuddyPress Multisite with sites dedicated to specific RSS feeds.  I did this to pull in the content for my users.  But they generate a 1000s of SEMOZ errors/warnings for dup content, dup titles, missing metatags. etc.

So does keeping the content help my site SEO less than the errors? The content is not under my control so I have no way to relate it to my keywords.

Any opinions?

I can recreate these RSS sites, so I will probably delete them to see what happens.
