I'm not sure it will do any good.

Those ISPs that care about the garbage their customers try to inject
already do prefix/as-path filtering.

Those ISPs that do not care today will not add bother to add a filter on
this well-known community value (... and most likely, the customer
router sending out unfiltered garbage won't have "send-community"
enabled either).
