As a Roblox developer, it is currently impossible to hide your inventory on your profile. Instead of going down the road of hiding or deleting assets, I think it would work to simply remove public access to one’s assets. In Settings under Privacy, there should be an option to either limit access of an inventory to trusted individuals or to hide it altogether. The site should additionally omit results of your assets from searching your username in the Library.
I’m currently dealing with a situation where people are stealing my assets and their main retort is that “anyone can go to your inventory and take stuff, it’s all free when you upload it to Roblox”. I really think Roblox makes it too easy for people to take Decals, and the critical Mesh downloading issue is still unresolved.
If Roblox’s own inventory is hidden, I believe we should be able to hide ours’.
