Tumbler.io is a team who have massive marketing budget, at least this is the impression I have from them.
Over $7,500 (0.2900 BTC) spent on the review campaigns.
Around $1,000 spent on signature and avatar contest.
Over $18,500 (0.5000 BTC) already sent to me for signature campaign.
Over $26,000 (I assume 0.7440 BTC) to some specific members (some of them refunded some as you know).
No doubt, Tumbler.io is the brand who are going to be the most unfortunate project on Bitcointalk community. They already spent a lot of money but when it was time to start receiving the benefits, a massive change in the rule messed up the initial plan that was set to execute. Things started to change and we had to make many changes, many business calls (calculated risks) - together or even alone myself as their campaign manager.
I can understand where you're coming from a bit, but in a different context, since I was about to buy thousands of dollars worth of link placements before my website got suspended.
Sometimes unforeseen events mess up the planning so people should take reasonable precautions to deal with the ones they know about so they won't become a problem later.
