I think i have found out why people only fav and never comment

Yes its something that annoys all of us but.... i do believe that people do it so the recipient of the fav has to comment on their page saying thanks, instead of on the comment if one is left

Why on the page?

So that if said faver is an artist who submits works, their works have a chance of being looked at bye others, and a chance of a watch

Thats how i see it any way
