Set an expiry date for player services

Hello Teebs,

Trades listed as "Player Services" never expire.

That can be nice... but some say forever and hard to say if they are valid are not.

What about :

- Dealing with them like standard trades (so bumping them like others, max every 6 hours)
- But with a longer expiry duration (e.g. two weeks ) ?

Would clean some of the mess.

I (obviously) support this

I had a situation where this created a bug that needed an administrator to fix.

I froze all my trades eight months ago to take a break from the game. On return, my Player Services listing hadn't expired, but I was unable to unfreeze or delete it.

I would also appreciate an expiration date for player services. Most of them aren't valid anymore (at least on hc nl) and often the creators haven't used the site for months/years.
