To those uncomfortable about IPs being collected: use a proxy while visiting forums.
About LPLockdown
A significant percentage of the IPs collected from here are dynamic IPs. There is no "sophisticated algorithm" which can determine dynamic IPs with 100% accuracy. Reason: mainly, you only have the following data: browser details, IP/ISP details, time details. Those are NOT ENOUGH to make a determination which is 90-100% accurate.
Other problems: Nicky is popular here, so managed to collect a lot of IPs from WickedFire. However, the IPs are mostly from WickedFire only. DigitalPoint and WarriorForum have a lot of marketers ranging from stupid to somewhat smart. Nobody has managed to collect any significant amount of IPs from there so far (yes, I am going out on a limb and assuming this, but I believe I am right).
Now, the truly smart people use proxies, so their IPs are never gathered. You cannot stop them from stealing your landing pages. If the argument is that it is to prevent the stupid people from stealing, there are a lot of stupid people coming from WaFo and DP, and there is no way to prevent them.
So, the problem is, you have a lot of "stupid IPs" which have never been collected, and the smart ones whose IPs have been collected will know how to access the right landing pages by using different IPs.
Regarding the launch: I see similarities with the Tracking202 launch. When they launched, Wes was banned from WickedFire for keeping users' data. Nobody trusted it. Then they came with the self-hosted version, Prosper202. This is what made the product "acceptable" to many. (Just to be fair: Wes or whoever it was from the Tracking202 team was banned because he pitched the product here. Nicky never did that ever, it has been others talking about his product). LPLockdown has the same problem because the core product and the data is being stored on someone else's servers. Until it is self-hosted....
Last words: at least, he had the idea to create something like this, and he managed to finish the product, and release it. The posts piling up on to this thread will just be more free publicity for him. And of course, Jon will be happy - 14000+ views the last time I checked. And the guys who want to rant, get their chance to rant as well. Good for everyone.
