I don’t like the idea of promoting competition’s products, but I have no problem sharing information or just asking questions and getting answers. Blatant promotion will be deleted like any other spam, but if there are legitimate questions or people want to discuss things openly I’m all for it.
Of course, my opinion is that competitors products are inferior so I’m happy to discuss that on the public forum 
For example, silicone is an elastomer. It will wear and tear and eventually fail. In fact this is so well known in the body modification industry that everybody you ask who is not familiar with Dangerous Things’ products will simply say that magnets are not permanent and they will inevitably fail. These professionals have never encountered our stuff.
