Sorry, but we didn't understand you at all. Do you mean PTC sites and other Internet Work Websites are register companies or not? If so, then you must know that all websites which we have listed in our "Good and Trusted Online Works" list as above are registered companies. Most of the sites which are listed in our "Promising Online Works" section are also registered companies. However, some sites as listed in our "Promising Online Works" section are not registered companies.
Running a coupons website can be very lucrative. Find a coupon niche, select a WordPress coupon theme, and then display relevant coupons on your site. When your audience uses the coupon codes or discount links, you will earn an affiliate cut for example you could set-up a site dedicated to iHerb Coupons or add a page to your website with Web Hosting Promo Codes. Coupon websites are quite high maintenance as they need to be constantly updated with new offers. However, if you build up an engaged audience and allow them to post coupons and discounts they have found themselves, then quite quickly your workload will reduce.
After observing the business model of Adzshareclub, we can clearly see that it is totally ponzi site without any back up income stream which can't continue to pay their all members. More than that, as per WHOIS record, they haven't mentioned the name of admin as "Dave Grol" there. So, it is totally fake site which even pay at the moment, can stop paying anytime soon in the future. So, stay away from it.
