1. You don't get trade banned for buying potentially stolen keys from the market.
2. You should post your ban appeal on TF2OP.

Donations have been disabled indefinitely.

What's the reason behind that?

Not all items have craftnumbers

I think this is a known bug.

引用自 Pretender：

Outpost has a huge userbase. Implimenting such a feature would require hundreds of bot account, and frankly, aint nobody got time for that. I think WH has like 86 bots or something like that, imagine Outpost's bot count. If this happened, it wouldn't surprise me if there was some sort of fee though, because there'll be a lot of time and money put into this feature.

Hence why it could be reserved for lv4 donators, it would give more incentive for big traders to donate. It wouldn't be cheap but it would be worth it. 50 bots with maxed out inventory could hold up to 100000 items. I'm not sure how much resources these bots would eat but I guess there's a way to run them so they use as little as possible (else WH wouldn't be operational). I also heard of extreme cases of item farming where someone had more than 5000 accounts and was planning to get 10000 before Valve banned him.

Either way I think this is something that shouldn't be dismissed right away and should still be considered. Is it worth it, would it only bring problems? I don't know. One thing is for sure though, if bazaar.tf pulls this off properly, a lot of people will start using it.

Yes there are many things to take into consideration, still it isn't anything far-fetched or impossible. Just take a look at TF2WH and scrap.tf. Currently there are no proper sites for automated trading so if OP could do that, that would be amazing.

My guess is they got lost when migrating old data. I don't think admins can help you. You should add the owner of that trade and ask them who they traded it to and then add that person etc.

What happened to the history of those items?

We really need that video tutorial. QQ

I really hope Sneeza is considering such a feature. Even if it's for lv4 donators, since the site has a massive userbase it would require a lot of bots. At least backpack expanders are cheap..
