Thumbs down

The official policy of OEIS disagrees.

On you can read:

Question: Is there a rule of thumb for which sequences we want b-files for?
Amswer: Pretty much any sequence - the b-files are always useful.

Question: I would think that sequences that are too simple (like the odd numbers) would be excluded.
Answer: No, even the odd numbers have a b-file (useful for plotting one sequence against another, for example).

Question: what size of b-file is acceptable?
Answer: 100, 1000, 10000, 20000 terms are usual. But remember that the numbers cannot have more than about 1000 digits, or some of the programs will fail.
So just because it is faster to calculate a sequence than to fetch it over the internet, does not mean you should not submit the b-file.
