I am a scripter who does work for other people, and I am trying to avoid getting scammed, for this reason, it came to my mind to use my personal website/etc. so I can save the game scripts there, and then in the original game scripts, upload them through the link.
for now, there’s no way to actually do this without getting extremely complicated. if you’re handing over your work to your commissioners but don’t trust them, usually this exchange goes in this way
you show them the footage/proof of the work you’ve done for them
they hand you the payment
you hand over your work
you can also use middlemen to oversee this if the other party is not comfortable doing that. otherwise, there are no ways of doing this.
Also, after you are done using the loadstring, go and disable it under ServerScriptService, if not exploiters will be able to exploit your game easier.
