Yes, they all return the same filter.nostr.wine relay metadata.
Out of curiosity, do every https://filter.nostr.wine/npub relay publish the same metadata (NIP-11)?
Or are some crawlers not making use of the relays metadata?

So, a first step would be to educate the crawlers to get and use the relays metadata.
And later we can define allowed limits over there.
Do you know which crawler is misbehaving like that in order to ask it to properly use the metadata to identify uniquely your relays?
