No offense but the backing tiers look like something from almost a decade ago. Course I'm sure some will like seeing special icons or badges on their profiles but, I question how useful it will be at getting some funding. I don't see the incentive.
First point: Adblock does it for free anyways. Even if you impose anti adblock measures, it will likely backfire. I honestly will not visit sites that are locked behind anti blocker walls. Unless there is a pressing reason for me to lift a blocker (and I use 3 of them), I just don't see the reason. If things got so bad where everyone employed it, I'd just investigate ways to block their blockers and get around it. Advertisements are the #1 means of getting malware on PCs. Adblockers have reduced infection rate on my PCs to zero. If I want to find a product, I'll go looking myself.
If I'm this way, I know others are too.
Second point: Badges and titles are not enough. You'll reach a saturation point and then need to find some new methods. Building the TPU brand beyond what you've done so far should be more of the focus. I came from xlr8yourmac and TPU's design was friendly and welcoming because it was from the same era. However, since then TPU really has been slow to adopt new things. A good marketer could take it much further. Expanding TPU more into video and generating a real personality.
I'd like to see incentives for backing for a year. Something beyond, maybe even physical items. Look at how Star Citizen does funding for their community information shows. They give both incentives for the present and incentives for the future. What about partnering with a tech reseller to give a discount after 12 months of backing? TPU gets supported, the tech reseller gets increased business, and the backers get whatever they want at a discount. That is much more of an attractive offer to someone like me who would seriously consider it for the discount.
