Simplest Solution would be no longer combining multiple threads into the main giant wall post. Click the Everquest button on the main ECT site, it takes you immediately to the just top portion where you select what product you're looking for, be it accounts, plat, krono, items, etc...
This would allow sellers to maintain and compartmentalize their threads, and then bumps could technically be an unlimited market.
IE; Major account sellers bumping their thread 3 - 4 times a day would probably be more than enough.
Krono sellers could bump their threads 100 times a day if they wanted to without screwing up the rest of the communities threads.
Basically after you click "Everquest" from the main ectunnel.com page, you only get this and are forced to click one.
The top Krono sellers could stay "pinned" to the top, and then you can compete for the 3rd, or 4th, or 5th place or w/e but still remain on the "Main Page"
Oh, and I would keep the standard bump amount to be set at 3.
I just think the main issue isn't the bumping between two competitive sellers. I think the issue is the bumping between two sellers, multiplied by everyone on this site. I wouldn't say I was ever in direct competition with
@Ninjapickle (In fact, I've secretly sent him some business <3) because of A. I couldn't compete nor would I want to, and B. Because he's an awesome FV account seller, it wouldn't make sense. BUT, when I was still actively selling and he first came onto the scene, there was definitely a small bump war going on. But it wasn't me and Ninja going against each other... It was me and Ninja going against literally every other thread on this site to try and remain on the "First-Seen" area. (Sorry to tag you in this bro, but figured it's a good example for peeps xD)
I just think this is a good way to negate all of that.
