This suggests that she is being specifically targeted by someone or something. Moira and Krakoa would be the most obvious candidates, but then why would they specifically block Kitty? The assumption so far has been because of her powers, but that doesn't really make sense. As pointed out above, there are other teleporters who could enter any space Kitty could access, as well as other phasing mutants, Shinobi and Cipher (presumably) and they have not been banned. Kitty has also been allowed on the island by accessing it through physical travel, if this were Krakoa keeping her out why would it let her on its shores? The thing with the Tower, also, is that although it is intended for Nightcrawler, the implication is that at some point he will open it up to the other mutants of Krakoa when he has formed the mutant church, so there is no real reason to permanently prevent Kitty from entering. So I think Kitty is being prevented by using the gates (and so far from being resurrected) by someone with specific reasons to target her that do not have to do with her powers, possibly for personal enmity or a grudge, and this someone would have to have either high level access to the gates and resurrection protocols or the ability to affect them undetected. The problem is I have no idea who that could be ¯\_(ツ)_/¯.
