I don't think a limit is needed so long as you have common sense and know how to utilize multiple villains. Billy's articles have way too many villains for a realistic series, so I'd use that as a measure for when you're going overboard. I'd say don't use more than 13 villains in a 13 episode season for example, 10 - 13 is about the most where I think you can pull it off well though (like the Sinister Six + the Enforcers, plus about 1 or 2 other villains is less than 13).
