Bernie,
I understand your frustration and your concerns.
Players will quit for many reasons... protecting an average, falling behind, having a bad day, etc etc etc. There are as many reasons for people to quit as there are people who quit. It is a fact of WGT.
There are a number of solutions. Join the WGTLS ladder site and play those who realize there will be consequences for quitting... only play with friends and acquaintances... play solo / tournaments only. These ways you (usually) don't get players who quit as you would in a randomly selected 'pick-up' game.
Having said all that, please allow me to remind you that calling out players by name in the forums is actually considered a more egregious breach of etiquette (and the TOS) than prematurely leaving a random multi-player game.
Please edit your post (with the names of other players omitted) before the forum moderators (such as they are) have a chance to come in and change it for you.
I am not trying to be mean or denigrate you, just offering a bit of advice. I hope you take it in the spirit it was intended.
Ciao!
