Having now run several store cards, both permits and fronts, I have a couple of observations.
1. Store setup scripts.
There are clearly people running scripts, or something similar, to start a store on a spot. They sit right on top of your store, for hours. One time, I came to my store and there was a lvl 16 player sitting on it. I came back 2 hours later, and the same player was sitting there. My store front was going to expire, so I had to attempt a reset. Quickly typing and clicking, with at most a 2 second window, yet they grabbed the spot. Clearly some kind of automation was running. WHICH IS A CLEAR VIOLATION of the TOS.
Now, server side, this is easy to detect. The player in question would have had thousands of store attempt failures in a row, at a very high rate. Very easy to detect.
I am quite willing to challenge my typing/clicking speed against another human. However, against a program that is a waste of time.
2. Meso seller spammers
These are the little nubs that sit in FM1, CH1, and spam out "mesos for sale here". With a web site.
These again are easy to automate detection of, and nuke. Geez, they say the website name in the spam. Mention that a few times, and BAM. I know that in the end it isn't that simple, however, it takes a reasonably small amount of effort to continually update this.
Get rid of the meso sellers, and you remove one of the main forces behind hacking.
3. FM Mafia
FM King ends up with all the stores in FM1, CH1. Hmm. Having gotten a spot in there after a server reset, keeping that spot was impossible. Script runners are behind anyone who is not "FM King". This makes anyone with the FMKing tag suspect as being part of an organized violation of the TOS.
As well, I have heard rumours of threats to kick people out of their spots. Mass defames, organized KS, etc. Have not experienced that yet, and will not take kindly to such abuse. Again, another violation of the TOS. (Harrassment.)
