Why are you being intentionally rude? Timescale is completely the right word and it is very telling that you didn't even bother to look up the definition, and in fact suggested a word that is more incorrect! I have a custom domain that is registered with very few select services and receive practically no spam. Are you trying to say that Anthropic should not be concerned with making their users' experience worse/better? Or that is simply our fault for being concerned about spam in our email inboxes?
