Experience with various email header fields and special responses indicates that most of the world, especially the spammers and robots, will pay no attention and might even take a response as evidence of a valid, responding, address. On the URI side of things, it works at all only if implemented and works completely ("gets rid of") only if almost universally implemented. You have not offered much (any?) evidence that would happen. So, bottom line, Larry's note notwithstanding: (1) drop# as a scheme name violates the specifications in 3986, including parts of those specifications that were, IIR, enforced to force URNs out of a direction that there was otherwise some evidence of consensus (among those who wanted effective URNs, not the community as a whole) they should go... specifically that anything following "#" had to be treated as a fragment as 3986 defines fragments and not syntax that could be interpreted as part of the URI. (2) There is no evidence, at least so far, that major browsers, web servers, or email systems would support this. That is independent of whether the scheme name were "drop", "drop#", or something else. Normally, that consideration might not count for registration, but, when you make a sweeping assertion like "gets rid of..." as a significant justification, it seems to me to come into play. (3) If "drop#" were allowed, we'd have to spend time and energy, not only reconciling that with 3986 but sorting out whether it had any relationship to a possible future attempt to use "drop" as a (more conventional) scheme name, e.g., whether the latter would be barred or treated as a completely separate string. The latter would almost certainly cause confusion, perhaps being put forward (or just used) maliciously by precisely the actors against whom you are trying to push back. (4) None of the above has anything to do with whether "http" is, or could be, a domain name (or domain name label), much less with whether "drop#" could be (it cannot -- see the syntax rules in RFC 1035). Recommendation from someone who is sympathetic with what you are trying to do (whether I think it would accomplish much or not): Drop (sic) the "drop#" idea. Move toward registering "drop", "dropno", "dropnumb", "dropnumber" or something similar. Then, and most important, pursue the concept, not the name. If you need the particular string/ name/ brand for this to succeed in any substantial way, it almost certainly won't. best, john
