Ok, I am going to try and explain something that got another guy destroyed when he tried.
If you want to post a crazy good batch to the forum so everyone can get a piece, that's your call but what you need to understand is your not just sharing it with the forum. You are sharing it with a lot of other people who have never even heard of the forum let alone contributed in a meaningful way to it. There are scrapers (I'm not sure of the technical term, maybe crawlers. whatever) that scan this and the other forums looking for hits and when it finds one it posts to another site while also sending out notifications to anyone who's signed up for it. One example of this is Hit Notifier and if you go to that site and look under "20 Previous" you will see that MTC supplies 99% of the hits. This doesn't really matter with surveys but any $12+ batches are going to get destroyed, and like
@C to the J said earlier, once a good batch gets hyped like that it will get scammed and we all lose out. The only way I can think of to get around this (other than not posting at all) is to not use the "export" feature to share good batches. That's what those sites look for when "scrapping" the forums. Instead just type out the Requester name. It's not difficult to use that to find the batch. I'm not sure if these sites can recognize panda's or not but just to be safe, stick to req name. An extra few seconds of work may end up saving you and the other forum members a good bit of money. Anyways, that's my take on this, do with it what you will.
