Still no, Charr.
Although I would say that when the subject has been discussed in the past, Thomy has said that he doesn't think that there's a problem with an oversupply of items in the economy.
If you want to help with this then you should try to make the case for why it's a problem.
The reason I'd still be against this specific way of solving the issue, is because people would only donate junk to it. Having a huge supply of junk items in the economy doesn't hurt anyone, so reducing the supply of those junk items wouldn't help anyone either.
What we need is to reduce the supply of items that people are actually interested in, so that there would be a reason to put effort into trying to get those items. Charr's solution to that was to have a whitelist of which items can be donated, which at best would lead into a staff controlled economy and that's not desirable either.
