Here is what I have gather concerning Fuininjutsu:
1. Absorbing: I have seen someone argued before, that characters with the ability to absorb chakra, are able to do it to Sealing Technique. It seems that this is false. Sealing is one of the exceptions of being cancel through absorption because of the way it "acts". It has the ability respond through certain commands/demands and even used to counter/block Chakra itself. The best evidence, to avoid elaboration, would be Killer Bee's

. We know that when physical contact is made in absorption, any chakra-based/used chakra should be eaten up. That whole fight was demonstrated in Kisame vs Bee and you can see it in SM Naruto vs Pein. If absorbing the seal is possible would mean that the seal for Naruto and Bee should of been broken, thus removing their tail beast from their bodies. Thus said, Sealing Jutsu CANNOT be absorbed.
