They tried recaptchas at JetBlue for certain instances where users pinged the system frequently (indicative of bot use). Not sure if it is still in place. Talking to some computer smart people who know some of the bot guys, all the guys with good bots have bots that can beat the recaptchas, so the only people it really affected were guys who were manually updating flica windows frequently.

The "cartels" are also still a problem at jetblue. The same guys seem to immediately pickup the trips with a bot, trade with each other, then dump what they don't want into open time. Many times a trip will be in and out of open time in an instant, then appear on the trade board or dumped into open time again if they end up not wanting it.

Supposedly management was trying to crack down (partly because it's a violation of flica terms of service, partly because there are a lot of complaints about it). Not sure if anything ever came of it with regards to discipline, or how much it still happens.
