Below will be the best way for people that want to run an effective shop without having to report a million scams and griefs. First to run a shop you will need to be a donor with TPA of course. Build your shop at the very bottom of your island, as in nearly about to touch bottom and die. Having /fly will be a major plus of having that. If you make the shop like a box shape and make it all out of blocks you don't care about then people can grief all they want "and maybe they'll fall and kill themselves which would be hilarious". When it comes to being scammed the only solution for that is to take the payments first always. A scammer will make you feel like your the dishonest one by making you place the merchandise first but never do that. Odds are people that run a shop have more to lose and don't want to be banned for scamming. Same goes for casinos and such, if you use lockette to protect the important things and make the shop/casino far from you actual island then you absolutely won't have to worry about griefing if built right. Comment if this actually helps you!
