I've added a new category to the bottom of the reports, "Little Original Content."
This covers two areas:
People who retweet 70% or more of the time
Of course, some people do find the best stuff out there, but in general, if someone is only ever RTing things by other people - why not just follow the other person? This is also something that is done a lot by spam bots, to make them appear ‘more human.'
People who post quotes more than 50% of the time
Similarly to retweeting, spam bots often intersperse their crap with quotes. It's a zero effort way for them to have ‘fresh' content. In reality though, if they're quoting Epicurius, this probably isn't something you need to be getting second-by-second Twitter updates on, the guy's been dead 2300 years!
That said, as with everything on the reports, there will always be those you choose to follow that fit into the above categories (eg, I follow a couple of accounts that post nothing but quotes). Just click their icons & they'll be saved.
If you don't want to unfollow any of them, simply click the headings, & the the entire category will be saved. As easy as ever!
