If you're accepting multiple addresses, isn't that... cheating? In that sense, the bitcoin address 1QBDLYTDFHHZAABYSKGKPWKLSXZWCCJQBX is the longest vanity address generated.

A vanity address is a special address that someone can use. To that end, you must generate a multitude of private keys and then check whether the corresponding address matches the pattern you seek. It is much easier to just make up an address and calculate the appropriate checksum which is what likely happened here (it's too long to find otherwise). In that case the user that created the address does not have the corresponding private key. This is called a _burn address_. I'd only call an address someone can spend from a vanity addresses.

Unless there is a transaction spending from that address, I doubt it's been properly generated. You can easily generate vanity-like addresses using sites like https://gobittest.appspot.com/ProofOfBurn , but you won't get the corresponding private key.

It's impossible to say for sure what's a vanity address and what's generated purely at random, but 1CFBdvaiZgZPTZERqnezAtDQJuGHKoHSzg is 34 characters with no digits in it other than the initial '1'.  That may well be a vanity address.  Then again on average 1 in every 515 34-character addresses you generate won't have any digits in them other than the leading 1, so possibly not.
The address with the longest initial list of lower-case letters is 1yaniraswqyghuJKCRrGwJUA2HakWtRad, and is clearly a vanity address since it appears in the same transaction as many other vanity addresses.
