One of the Top 5 Social bookmarking website – Stumble Upon a website which offers you to Connect, Meet and Share, has now started banning all the websites which are trading in exchanging votes/ stumbles etc. I just found that they have banned http://suexchange.com/ from stumble upon now because they mainly deal in stumble exchanges only.
As per the TOS of Stumble Upon :
Are incentive programs allowed? Someone asked me to rate their web-site?
StumbleUpon does not allow personal accounts to be used for the purposes of incentivization or promoting sites. This would be considered a breach of our Terms.
The practice of sending PM’s encouraging or inviting other stumblers to rate/review sites in exchange for reciprocal reviews/ratings, monetary, or any other form of reward is strictly forbidden.
The practice of actively soliciting a rating or review for a site is also forbidden. Should you receive a PM, or encounter forum postings that breach this rule, you are encouraged to report this via feedback.
Accounts participating in such practices will be deleted and banned, and the related sites deleted and banned from the system.
Suexchange used to offer points for stumbling others websites and in return you get back stumbles, though i dont understand what is the use of stumble upon because one of my fun[humor] related website gets around 4000 uniques/day from stumble upon but not even 0.01% stay more than a couple seconds on my website and just move on, which just leads to waste of bandwidth for my website and lots of useless impressions.
This clearly shows you should never try to fake some system which can deliver you great results when used legitly. Learn How to Stumble a website
