Viewbug has no concern for it's members. When the site was free, it was much better because there was no limit on anything. I created 140 groups. Now each member is limited to 3 groups. Contest prizes used to be as much as $500. Now you received t-shirts and worthless stuff instead. On rare occasion there may be a prize of 50 or 100 dollars. There are at least 250,000 entries. Most winning photos are horrible, the results of unskilled photographers, and/or just downright nothing.
For those of you that are new to the site, and think it's so good, just give it time. Many of my friends thought it was great at first. Now they are on other sites that are at least honest and don't draw winning contest photos out of an electronic hat. Seriously, anyone would know 300,000 photos are not going to all be looked at.
As a general rule I'm very positive, and am a happy person. However, it has been a nightmare the way Viewbug has ignored problems and ignored members. About 100 of my friends are more than disenchanted with the site. Most of them have awesome photos yet never win contests or have a photo featured. I'm doing this for them. Many have had to block other members that harassed them. They can at least feel some consolation that a friend is telling the truth about Viewbug.
A free site that focuses on selling your photos is RedBubble. If you hope to sell your photos on Viewbug, it is unlikely it will happen. Out of 300 Viewbug friends, 2 have sold one photo each. Viewbug focuses on getting the $60 membership. Everything else is secondary.
