Bots and long payment delays, by bux.to
This is the first and most used scamming model, introduced by the leader of scams, bux.to. Referrals which somehow will stop to click at the same day and 1 year payment delays. If you dare to protest (where is my payment, I am waiting for months?) first *** kissers (= forum moderators) will attack and then ban you (=forget payment).

Pay to get paid
Do you want to receive payment? Invest first the 50+% of your next cashout. Non-investors will be deleted.

"Instant" payments
Instant payments script will be ready soon. Estimated time of release is February-31! Premium members will be paid instantly only, when script will be ready. Six months later: Script will be ready soon, be patient (and keep investing of course) we are working on it.

Run a dozen sites
No need for business plan or initial capital. Just open 5, 10, 50 or more programs. Simply, when it is time to pay, change TOS (= payment limitations etc) and after that abandon ship! Not a surprise if out there we can find 1000 scam PTC sites owned by a few people... Just a sample below: ~100 programs are listed - all scams - by 5 different owners, only!
Famous scams used it: bux3, gptnetworks, titancash, northowl network, JJ (Jeffrey Johnson)

"Hit and run", by 15 year old kiddies
With ready script packages - buxhost at the moment - 13-16 yr old kiddies scammed many members. If a kiddie knows php, scamming is bigger and more painful. Most "Hit and run" scams will survive for a few weeks only. Therefore their reputation is low.

Reset balances/referrals or even better delete all members
Easy and simple: Delete all payment requests, reset balances to zero, remove all referrals. Even better is to delete the entire database and make a new "fresh" start! "Nothing happened" according to scammers, just a fresh new start for us, with your money. Register and invest again!

Promote via a forum - cooperate with the owner of the forum
A few years ago it was ptctalk.com (not .org). This famous forum, helped many scammers to promote their programs. Taketheglobe, thinkbux, crewbux, foxcash, xclix and many more PTC sites made their first steps there. Now it is earnmoneyspace/emoneyspace. Cashium is the best example. Seems that in some cases there is cooperation between PTC owners and forum administrators/moderators (not always the most trusted members) in order to mislead members and make them to believe that investing in specific sites is more than safe.
