I don’t know whether to say it’s ironic or not, but reading this, I was
thinking “IX route servers may not be involved in the propagation, but I know
from past experience that HE intentionally propagates some peer routes to other
peers.”
And then your example leak has HE in the path. This may w

You’ll need to be very selective about the IP ranges you apply that filter to,
or more likely, just do it and make sure have one or more default routes to
