The emphasis is on the inability (not) to do so, as opposed to the possibility (can). According to all the sources I have informed, it is more regular to use the separated version in those cases. This is also more understandable for international users, especially as a warning that it is not possible. In any case, can not is perfectly fine to use, based on all the checks that I've done. If you can come up with different trustable sources where it says it's not, you can send it to Special:Contact. I think you should reconsider what you say about others when you don't have anything to back it up with. Saying others can not spell anything right while not being able to defend yourself with anything comes up as incredibly rude and condescending.
