I don’t know. I do know that Aoda and Audley threads are removed rather frequently, in part because they both do make bootlegs of other brands. However, they also make original designs that they license to other companies, so its a real grey area regarding those two brands.
At the same time, there was a thread about yet another bootleg yoyo that was left intact and untouched by moderators. I think this was because a deliberate effort was made by all participating parties to avoid the brand name AND a place to obtain it. All I can say is the thread motivated me to purchase the yoyo in question, which is now making me really want to buy the “real deal” and others, all from YYE of course.
I think as long as you do things like omit locations to purchase it in the thread, that will go a long ways towards keeping the thread alive. It’s a courtesy to YYE to not post links to competitors. It’s also considered good form to not post about products that YYE isn’t currently carrying. The reasons are a bit vague but I think it has to do with preserving possible business going forward or at least maintaining options.
Without hearing back from the moderators, it’s difficult to say. Also, because all the moderators are very active here, I would find it a bit odd if they didn’t at least give a very short reason for the removal/deletion just so you can understand why.
