There are traders on here that I prefer NOT to interact with for various reasons, and traders that I prefer. It'd be nice if I could specify a list of each, or at least a list of the traders I don't wish to deal with and they could be automatically excluded from my trading opportunities.

Maybe I could turn that list off and on, so if I'm really desperate, maybe I could include my "avoided" traders in Trading Opportunities but they wouldn't show up unless I specifically indicated they should.

I agree. I'd love the ability to just "hide" specific traders. For example, there are a few people on here that have active wishlists/tradeliests, log in regularly, have completed dozens of trades in the past, but refuse to respond to any trade requests or messages. If we won't force those folks off of the trading side of deckbox, then I'd at least like the option to ignore them.
