They are currently a proscribed group, so yes, that is included in the list of things you probably shouldn't do. You're not going to get killed for it though. You're probably not even going to get arrested in most cases.

Whether or not they should be proscribed is a different issue. The best course of action is probably to wait for the courts to decide. Pressure groups damaging military assets probably aren't going to be well received by the public regardless of which cause they're for.
