My interpretation of this list is not necessary about IXPs or not, but
focussed on 'peering' in the broader sense of the word.

If you are *not* directly peering with 6830, on the majority of your BGP
sessions you'll probably want to block announcements that have 6830
anywhere in the AS_PATH, except on your 'transit' sessions.

Whether 6830 is present on IXPs or not is not relevant in this context.

Describing what should be done in English is really really challenging!
Pull requests welcome :-)

Kind regards,
