Hey guys,
A friend of mine owns and operates a small pay site. It is just that - a small niche web sites like thousand others on the net. He has a webmaster program but never really promoted it. Untill recently something happened...
He got a webmaster started promoting his web site. So far so good. And here starts the mistery... Here are some facts I just learnt and I feel not comfortable with so I decided to post them here and may be you can give some ideas. I *think* there is some sort of a cheat there but I know nothing about pay sites and how they operate and I don't think my friend knows any more though he operates his small pay site

Anyway, the facts:
1. Sales are not constant. 1 sale today, 20 sales tomorrow. No sales the day after tomorrow... then again and again... come and go in waves. Not a constant traffic.
2. ALL SALES are 3 month check sales. All 100% of them. (this rings bells in my head and i told it my friend). What is the possibility of lets say 250 3 month check sales in a row from one webmaster? I would say 0,000001%. But then again - I know nothing about pay sites
3. There are 10% revokes on these check sales according to the processor stats.
So, where is the catch here? Are you suspecious of a cheat? Should he contact the CC processor to investigate this or what?
Any advice will be appreciated.
