Mixed feelings. Adding a small fee would almost certainly help with the spam problem, but it also might limit adoption. People expect social media to be free. (OTOH, getting a handle on spam might even help with adoption, so...)

The problem might be solvable by increasing the resource credits that are needed for posting, or maybe just add filtering to condenser so we can customize our views by ignoring posts from low-reputation authors, low numbers of words, or any other criteria that people might come up with. Another option might be some sort of "freemium" fee, where your first (insert arbitrary number) posts are free, and they become increasingly more expensive after that.

Every time these subjects come up, I always fall back to the position that it needs to be studied by professional economists and/or game-theorists and done carefully. We have a history of "shooting from the hip" and then reversing course a year later.

I guess my position would be: (i) Add filtering capabilities to condenser; (ii) Use the SPS to fund a game-theory/economics study to model it and make a proposal for optimizing blockchain economics (assuming there is community support for it); (iii) use the SPS to let the community vote to approve (or reject) the proposal; (iv) If approved, implement - use the SPS to fund development.

Edited to add: The first two users I checked are both using delegations from Steemit for their posting. Maybe we just need an efficient way to communicate abusive accounts to Steemit so they can quickly remove the delegations.
