As a person who enjoys an fbsm type of service I use gumtree quite a lot but the one thing I do notice is the totally pointless photos posted on the advert. These usually contain the following images
1. Candles
2. Flowers with candles
3. A pile of stones balanced on top of each other
4. A pile of towels
5. Towels formed in the shape of swans ( Thai shops especially)
6. A relaxing beach scene with Palm trees.
7. Hands rubbing oil on to someones back.
8. The massage couch in the room (which more often than not is not the couch or room you will have your massage on)
9. Images of Buddha ( Thai shops again)
10. Sign saying " Don't panic have a massage" or simular sign
11. A picture of some lotion bottles
12. A cartoon type of picture of an oriental person massaging another ( favourite with Chinese massage parlours)
13. A picture of a male being massaged who is that toned and good looking that he's obviously a male model.
14. Signs telling of the benefits of having a massage.
Some gumtree adverts have 5 or 6 photos posted. You can guarantee it will contain some of the above images.
Feel free to add to the list.
