You can & definitely should strip those community values on announcements you receive from EBGP peers. Interesting things happen if you let others turn your routing policy knobs when you think they can't reach them.\
Agreed. Likewise, when you receive communities (and MEDs, ugh!) [if possible] you should reset them (v. employing 'additive'). Unnecessary propagation and/or uniqueness of many attributes (especially transitive) can that go unnoticed often have a significant impact on efficiencies of BGP update packing -- which subsequently impacts convergence, CPU & memory resource utilization, etc... -danny
