Based on the current stats I don't think bitnami is much of a problem topic at the moment, so I would be in favour of treating each question on its own merits, rather than issuing a blanket ban. 

The [tag:bitnami] tag only lists 10 questions marked as such this year and a search for questions containing bitnami as a keyword (using: [`is:question bitnami`](https://serverfault.com/search?tab=newest&q=is%3aquestion%20bitnami) as the search string)  only returns a 113 results, not a huge number. 

Roughly half of the questions which mention bitnami have been answered. ([`66 / 113`](https://serverfault.com/search?q=is%3Aquestion+bitnami+isanswered%3Ayes)) 

Only a handful of questions has been down-voted with for ServerFault quite a few even ([`57/113`](https://serverfault.com/search?tab=votes&q=is%3aquestion%20bitnami%20score%3a1))  scoring one or more up votes
