I agree that this is a good way, because you can see which prefixes a network intends to advertise and cross-check that with the prefixes you accept.
An extra hint for the original poster, the command line widget to inspect the prefixes listed inside IRRDB against this origin asn :
peval -h whois.radb.net 'afi ipv4 AS15169'
peval -h whois.radb.net 'afi ipv6 AS15169'
