Hi -
You might change the subject title to 'Mongo Bongo, Crazy Frame Sweeps, etc.' and that will get more people to look.
Here is my own experience with these sweeps. When I first started sweeping, I looked at these sites, thought they looked 'wrong' and stayed away. Then, I thought I must be overreacting and entered on all of them for about a week. I came across some articles online about the same time that mentioned sweeps created just to get your info and when I looked closer at these, I saw no affilation of any type (no BBB, NOTHING, everything was very homeade) and often found multiple spelling errors which is red flag. Finally, the last red flag was a cooking sweeps (gastro weekly (?)) at first it looked legit because of all the reader comments and posts, but when I looked closer, everything was created one person - the admin.
Another one not on the list: max beauty
These are so similar that I've wondered if they are created by the same person.
Hope that helps.
