The buttons are usually molded into a silicone sheet. The silicoen
starts to de-polymerise and that's where the liquid comes from - it's
silicone oil. You can clean it off with alcohol, but that just gives you
enough time to look for a new remote control.

Having spent many years on ebay, I'd say your definitions are fairly accurate. Over the last year, the electronic stuff I tend to look at falls under the category of Untested (or a 'active' statement - plugged it in and nothing blew up/light came on). Most of the postings seem to be done by people who are clueless about electronic things. They stumbled on something electronic and want to make a buck on ebay. The garage sale recyclers are some of the types that drive me nuts. They find something that 'looks complicated' (e.g. a older ham transceiver for example), with the 'untested' label, and list it for the price of a 'working-tested' unit.
 
If you are into vintage TV and broadcasting, you may want to check out this site:

Some years ago, I helped diagnose some old TV sets and a vidicon on their mobile broadcast truck. At one point they had intentions of setting up a 'early 50's' broadcast studio.
Neat place if you want to get a look of early TV receivers from their inception through the 70s
