All of Pinecast's paid plans allow an unlimited number of podcasts. Each podcast gets its own feed and website; all podcast settings are unique.
For Demo users, a limit of two podcasts is enforced. Community users have a limit of five podcasts.
If a paid account is downgraded but it has more podcasts than allowed by the limit, no podcasts are deleted. No new podcasts can be created, however, until the number of podcasts in the account has dropped below the limit.
