Which offers work and which do not?

I have completed two of the Offers and received no compensation.

-Game of War Fire Age (Stronghold Level 5) ($3) -Speak Up! Green ($1)

When I asked the LootMarket.com Help, Techies said "Hello. We do not provide support for Offers, and cannot investigate whether an offer has been completed."

Has anybody received compensation for their offers and if so, which ones? Maybe we can help each other avoid bogus offers in this post, since LootMarket.com is not moderating the bogus or flawed offers?
