Those trades are all open for the same reason, to sell weapons for a scrap. If you don't want your trades closed again just use one trade and list what weapons you are selling.

From the second link:

Your ticket will be addressed as soon as possible. As you may imagine the staff receives hundreds of tickets daily and it takes some time to get through them all. How fast a ticket is responded to is subject to the assigned admin's availability — among other things — but rest assured you will not be ignored.

Adding staff members or posting about a ticket here won't help speeding up the process so please don't do that.

It's pretty easy to tell someone is trading here as every post is looked at.

Check your trading history. Look to see which of the users you have traded are marked on steamrep.
