BLF threads would not disappear because they are singular threads with a lot of creator and community content within. Google forms is new to the forum but the concept of group buys is not new in general.

Even some of these group buys never materialize and I think is nothing more than a manufacturer gauging market interest for free. We are the kickstarter of flashlights. Lots of models to learn from. Banggood and others are surely capable to replicate something less intrusive but why would they? If I make something for sale I would want my thread hyped up dozens of times per day/week too. The size of the thread per say is less an issue than threads being perpetually at the top just for transactional purposes. (which is not really the purpose of any forum)
