Hi! I've been trading for a while now, both here and on Encora. A few questions.

1. Should proshots be given away? Personally, if anyone asks me for proshots (like the Les Misérables 25th Anniversary concert), I just freely give it away. Should I expect this behavior from everyone (unless, of course, the trader says that they don't give out/trade away proshots)?
2. Should file upgrades be given away? Again, this is something I freely give away personally. If someone tells me that they need to upgrade their Youtube rips into VOBs, or they lack one file, I just give it to them freely. Should I expect this behavior from everyone? Can I message people that I need file upgrades without seeming entitled?

Edit: I'd also like to add that I've experienced having both freely given to me when I requested them. I just want to know if this is to be expected from everyone, or if it's a case to case thing. I can't see the comments yet so idk what everyone's response is for now.

I'm asking these so that I can follow proper trading ratios when someone requests a trade from me, and I know what to expect from other people's trading behaviors.
