It's absolutely legit. Been doing this for years. This particular site I've done for like 7 months, it's still small and new I think it has potential so I'm trying to get more participants. If more anglers join the pots will get bigger and more place slots will get prizes. Right now it's winner takes the whole pot, all done through PayPal.
You can email the creator directly, it's not a big company or anything. Just another angler that started and runs it.

Seems like a cool guy, I email him all the time with questions and suggestions. If you join, tell him chrisper4694 sent you. And make sure you take good 'bumped' fish measurement pictures. I can show you some examples if you want.
