I propose this as browsing experience is boosted using ad block plus. There is a block function for exactly this sort of thing.

You should be able to import and export chat blocklists and view who is blocked.

At the very least you should be able to export block list to see who is on it.

Though I feel that Jita local needs some kind of control, I don´t like tradeable blocklists. Idea itself is good, but I have seen it already been used wrong. One day one person made list, put it on internet and traded it. First free, then she asked isks for it, which is not problem. Problem was, that she put many honest traders in that list (including one of my alts) (yes yes, how many honest traders there is in local, heh, anyway) and it really harmed marketing as there was no way to correct things (as being blocked).
So I believe that tradeable blocklists can become just tool to manipulate and block persons out of chat, even without their knowing.
Real scammers just make new character, but if you are honest, played with toon long time, it really hurts if you can´t use it on local anymore.
It is very easy to block. Just use that and make your own decisions.
