Great point.

Also, I think a problem is one person can only send one like.

Returning to my example, I'd like to be able to give the litter picker 20 likes, and maybe the Selfie uploader 1 like.

I think there has to the option of another accreditation technology which runs across social networks.

It's an area I'm interested in and looking to do my next project on...
