We are looking into this, we'll let you know when the issue is resolved.

The same item can not be listed more than once, thus excessive > 1. Multiple variations of the same item can be listed as if they were different items, but at the end you will just waste slot/trade space.

I removed all of them. Thanks for letting us know.

Well, Valve is the one to blame here. This is why phishing also will not stop, people can create an infinite number of accounts.

We do our best to ban these accounts from the site, it is not pointless to try and protect our users.

From the rules page:

No cash or game trading with new accounts. Your account must be at least 2 years old and have at least 20 non-free games before you can start trading games for items or buying items for cash on the website. Exceptions will be made on a case-by-case basis at the discretion of staff.

Besides allowing exceptions, the Steam API is not reliable enough and we can't afford to spend thousands of API calls every time an account lists a game on a trade - API calls have a daily cap.

No begging.

Check your inventory history.
