Yes, I think we should have the option of both. I would suggest setting the price for mesos based on the cost of AP resets. The trouble with the shops that are effectively free is that everybody has one, and everybody considers it their right to always have it set up in channel 1, and it has caused so much conflict. People always have the option of using the forum to sell things too.
Nothing needs to be done. If you jump glitch, then you're an asshole, because in order to get a jump glitch spot, all that is needed is for you to be more of an asshole than anyone else who happened upon that spot before. People should not be rewarded for being more of an ass than anyone else. Soon, channel 2 will be full, and then channel 3, and channel 4, and the need to have a channel 1 spot will become less and less imperative. Get with the times. Or wait 24 hours O.O
As a scumbag shop jumper, I have to say... I'm a scumbag shop jumper. You can avoid having a shop jumped on your shop by filling up the minimal space between 2 shops. Instead of taking more than one spot. It actually prevents this shop glitch. So it's kind of a good thing in a way as well! I actually do this when I actually try for my shop spots and are never stolen because I don't always get the best fm spot and camping out for one is nice too, if I'm online at that time. In fact, I'm beginning to think more people are doing this filling up space thing (GOOD FOR YOU), because u see me with an fm 11 spot most of the time.... even tho I'm scumbag.
