I don't disagree with either of you. Maybe the admin is trying to protect himself from users threatening to sue for a bad trade.
Probably at least one good reason for me not to regret Lestrade's never getting the traction it should have had.
Then again, I miss working on dev.
But I'll never focus on advertisting it.
It's there if people want to have a place to trade without relying on Barter, while still using a similar system.

I don't know what else there is to say. Invite all your friends, I don't know :-)
If we get more traffic, I'll probably get back to work on it a bit, if only to fix the bundle system! (But it's really annoying that no one contacted me about it on Steam chat or whatever when it started happening. Because of that, it's going to be more difficult for me to recover the old bundles. I can do it, I suppose. Just annoying.)

I don't understand your point. I'm keeping it to the minimum to make sure there are no easy scammers here.

This kind of information is indicated automatically on Barter, I believe, but not here because I chose to use IsThereAnyDeal's bundle database, with all its quirks and issues, in order not to rely entirely on BVG for everything. Stats show that while Lestrade's has a pretty good trading system (I always find it more practical than Barter's), most people use Lestrade's to fiddle with their game library, rather than send trade offers.
So it's up to you to mention region locks when sending offers.

More importantly, users are free to indicate their country of residence in their profile, so you can determine whether or not this will be an issue. :-)

Well that would mean releasing the source code on GitHub or something.
I'm not there yet. The codebase is a little dirty with plenty of commented out code. I'm not ethically against it, though. Just unhappy with the current state of affairs. It's really a heavily modded Wedge although 90% of the site's features are in a single place, code-wise. It's a pretty large file. Ahem!

It really shouldn't. My code clearly labels manually entered tradables as protected.
Barter is better for trading because there are more users (and mostly only because of that. I really don't like the UX for that site I'm afraid.)

FYI, I was finally able to fix the bug that stumped me a few weeks ago and caused many multiple copies of bundles to show up.

I've also removed all of the duplicates, and cleaned up many of the bundle errors.
Unfortunately, ITAD bundles aren't as 'clean' as those at Barter, but I clearly want to rely on ITAD only for these, because it allows for an extra source.
(Also, I don't want to scrape everything from BVG when I can avoid it, really.)

Wishlists imported from Steam (only those) expire after several months if the account is unused, yes.
As for tradables, I think there's something about them too. My goal was just to avoid ghost accounts, and tradables aren't deleted if entered manually, really. Are you sure you entered them manually here..?
Generally you can reimport from Barter, if you have an account over there.
