The only table I think bbPress creates is the one for importing forums/keeping extra imported forum data. Most of the data bbPress has are stored in WordPress tables, but all that data should be gone if you ran the reset forums tools(well except the forum roles).

Stored Database Data

If you are looking to delete users you can go into Users > All Users in the WordPress backend and then start bulk deleting users.
