I try the best that I can to provide valid information, but I don't have a rank yet. You may be stripped if you speak ; fluff, get into arguments, or if a higher ranked person decides you don't have a proper rank, or you may not deserve it.
Just don't worry about it, keep showing your knowledge and not try to care if you have ranking or not. It it a title, and doesn't make you unworthy.
I honestly think that you should help just because you want too, heck I wish I hsd a rank but it gives me something to work for. When I get one, it too will make the work pay off. Good luck!!
