Both of these stores are mine. The first was set up @ a server check and got there first. I set up the second store above it to the right on my mule. This was done in FM2, but I also did this at FM1 last server check and it was also closed by a GM. Here is a picture of exactly where that store can be set up, without a jump glitch, 100% legit. It is not farthest on the ledge to the left, it is slightly right from the furthest edge. I was told it is still "technically abusing a glitch" because they technically overlap at the corner. Stores allow for that, the store is too high vertically to interfere with that store.
just want to add a note that I've owned stores in the lower position that have been left alone for days in similar circumstances, so this doesn't appear to be something on which there is a consensus.
OK, we've tested properly and your stores are actually legitimately placed. Sorry, I believe this happened once before when I was the only member of staff ingame, so it wasn't possible to test it out properly with just one person - please accept my apologies. As for your mule store, please contact GM Cyndy about putting your store back where it was.
I created a video of myself making a shop in the same spot for fear of getting reported and banned for glitch abuse, even though it was legit. Hope this helps: Below is a picture of the shop after it was opened, as I did not capture that in the video.
