I don't how this information is of any relevance to regular users.

Pretender got it. You spammed YouTube videos on all your trades. The ban should not have been revoked and is going to be re-issued.

Trade Rules #1: Please do not make trades with...

The videos are irrelevant.

I don't know what URL currency is. So it's okay to trade for keys, then trade keys for paypal, but it's not allowed to trade for paypal directly?

I meant IRL currency. Trading gifts for items is OK because they are contained within the system itself, i.e. you are not exchanging money - if they were not allowed Steam would not give people the option to trade them for other items. Also refer to the next reply for more information.

?
So, I've been selling games against Steam ToS all this time, even when I traded for tf2 keys/other games?

Trading is expressly permitted by the agreement:

D. Trading and Sales of Subscriptions Between Subscribers

Steam may include one or more features or sites that allow Subscribers to trade, sell or purchase certain types of Subscriptions (for example, license rights to virtual items) with, to or from other Subscribers (“Subscription Marketplaces”). An example of a Subscription Marketplace is the Steam Community Market. By using or participating in Subscription Marketplaces, you authorize Valve, on its own behalf or as an agent or licensee of any third-party creator or publisher of the applicable Subscriptions in your Account, to transfer those Subscriptions from your Account in order to give effect to any trade or sale you make.

All I found is
Valve does not recognize any transfers of Subscriptions (including transfers by operation of law) that are made outside of Steam.
"Does not recognize" isn't really "severe punishment".

They do punish users, we have seen it multiple times before. One of our staffers does community management for games available on Steam and she confirms Steam acts very ferociously against people who exchange gifts for IRL currency.

How am I doing this, if I bough almost all of these games from Steam Store myself while they were on sale? Some of them I swapped for other games, which I bought in SteamStore myself or for tf2 keys.

You are buying games when they are on sale and reselling for a higher amount to other users. The money you are getting was supposed to be paid to the developers. Example:

Game costs $10. Big sale arrives, game is sold for $2.50. Then you (and thousands more) buy dozens of copies for $2.50 and resell for $10. These $10 would have been paid to the developer if you were not present.

You also do not own the gifts/games, you own a license of them. You have no right to sell them because Steam (or the developers) did not give you this right, and they are not your property.

I have no idea what you are talking about. If you were banned on the site it would have been because you broke our rules. But, as you can see, you are not banned: http://www.tf2outpost.com/user/76561198083743375

It is not allowed to trade gifts for IRL currency, that's why your trade was closed. Steam's TOS does state one is not allowed to sell subscriptions (i.e. gifts included), and they enforce severe punishments on those who do as they are literally taking money off developers' hands.

Someone with the gift must have their inventory browsed on the site for it to be added to the database.

A game must be added to the database before showing up in search results. If you can't find it then it's probably because noone on Outpost attempted to create a trade with it yet.

There should be a new "inventory" icon soon for each of the games we support.

If you have evidence of a scam attempt file a ticket on the site.

There's already an open report about this: https://steamhost.cn/steamcommunity_com/groups/tf2outpost/discussions/11/35221584501621423/

Creating multiple tickets to address an issue already in progress will not change anything.
