It would be very nice, when it is possible, when someone create a store for EasyBlogger, that they need to verify it with the avatar which created it, like a login code or something like that (so it can be saved in the EasyBlogger Logs and if something happen, the Real Shop owner can contact the EasyBlogger/Primfeed support to get that infos, to be able to contact Linden Labs with that infos “if as example someone meant i created it with an ALT for my Store”). It will make it more safe, that none will create a store where she/he isn’t the owner and makes problem for the real shop owner.
Maybe a way (if possible) could be, that only the Real Owner Avatar can create a Store which already exist in Second Life. If a Owner from a Store has Problems with her/his Account or so and made a new one (Avatar) that they verify it with Uploads from the Store, to show it is the real Owner.
New store also should be verify when they create a new and not already exist Store, like with a login code sent to this avatar, like some other second life social media does (i do not write them here, is advertising then).
So those stores can also be registred to this avatar.
Sure we all can never be 100% safe but it may help a little bit that no fake accounts steal already exist Store Names. If they add different stuff and all, customer will also be very unsure.
Maybe (if possible) it could also work, a second way to this first idea, a store will be public after one week, when the Avatar is often online and active, listed payment infos on the avatar as well, without it is possible, sure, but it's not very common for the avatar to be able to upload things, like shop logo, items and stuff (if possible to control that).
