Consider this! The actual strength level and infamy of any pirate is based on how visible they are.

Blackbeard is exceptionally strong, but he was pretty much unknown until he beat Ace.

Same with Buggy. People know the following things about him: 1. Roger pirate. 2. Supposedly Shanks level; he was said to be as a brother to him. 3. Broke out of Impel Down with a new strong crew. 4. He "fought" Mihawk and lived.

All that means that he would definitely be considered a threat. And he is, when you think about it.

With that kind of reputation, he'll be able to attract more powerful pirates, like the Impostor Straw Hats and Caribou and Coribou.

So, besides for being a legitimate fighting threat (crew-wise), he has reputation.

What the hell else do you need to be considered for Shichibukai?

-Especially- with the group in disarray as it was.
