Prediction comes true.

I don't remember names, so I cannot tell you who predicted this, but whoever it was, (s)he was true all along. People are starting to sell the free newbie stuff to newcomers for L$. In welcome area no less, right besides the No selling, advertising... sign (the person here rezzed and moved a plywood box over the sign after people mentioned it).

We need PERMISSION_CHANGE_PERMISSIONS to be implemented, right now, and defaulted to FALSE. Not in a few weeks, not for next month, I mean now. My greatest fear is that people start selling my free stuff for money (that would be copyright infringement, but eh it's bound to happen).

It's a tough problem to fix with software because people can always:
(a) show products, accept money, and give them by hand
(b) make a vendor to directly sell them, circumventing the buy system

Some options available:
(a) Report the offender, continue to make examples of them
(b) If possible, put "FREE" in the title/description and lock the item and make the item no-mod - I realize this may only work for attachments, but it prevents people from linking an invisible prim to it and renaming it. Newbies could at least see that it's free.
(c) Better publish / advertise free item locations

I've been thinking about setting all my stuff no-transfer and include a "IM Jesrad Seraph for your own free copy" inside, but I still think I shouldn't have to work around that kind of limitation in SL

Do what I do in scripted stuff. Even if it's moddable, I set the name and description of the whole linked set back to what I want it to be called in the main (non moddable, obviously!) script. Has the effect of detering people from ripping you off by selling your freebies, and even better when someone tries to yank your free script out and put it in their product and it renames itself 'Kris's Free Whatever', description 'Not For Resale - Contact Kris Ritter if someone tries to sell this to you!'. If they take out the script, well then it ceases to function. Job done, scumbucket thwarted

We need an ll[Get|Set]Price() function.
This way you can do something like:
if (llGetPrice()>0) llDie();
Or:
if (llGetPrice()>0) llSetPrice(0);
etc.

Ooh I like that idea.

Shit. I endorsed Eggy.

I wish there was a way to make one particular script undeletable from a modifiable object...
