The only way I could see it working from a gameplay perspecitive is like the trade request button. Pirate meets trader, presses said button, trader accepts, pirate encounter happens over voice between those two. I think that would be great fun especially for people who enjoy pirate rp. It also gives people the opportunity to decline voice so no one is forced to deal with it and keeps the chats between 2 people rather than loud groups. Ultimately though this isnt an ideal feature for disco as implementing it would be a grey area (as in, possible just not done already) as well as it not being the right community for it, I feel even with the request option people will still get harrased with it and/or it will lead to harder policing of rules.
