If the OP wants answers specific to the Theravada tradition, then he or she has to use the Theravada tag.

If an answer can even be narrowly or marginally interpreted as being related to the tags, then it will not be deleted by the moderators.

If a user feels that such an answer is technically wrong or inaccurate, then he or she should downvote it. Please see [this answer][1] for references to SE policies on this.

For e.g. we had one answer which argued that *anicca* meant "insatiable" rather than "impermanent", but this answer was downvoted and not deleted, because it is at least marginally related to Theravada, but the majority considered it to be wrong or inaccurate or unorthodox.

On the other hand, a hypothetical answer that states "there's no such being as the Manjushri Bodhisattva according to the Pali Canon", for a question on Manjushri which is tagged Mahayana or Tibetan-Buddhism, would be clearly off-topic to this tag, and may be deleted by the moderators.

This moderation policy is different to SuttaCentral, which considers "Anicca doesn’t mean impermanence" to be an [extremist view][2] that may cause the user to be banned. On BSE so far, we do not have a policy for moderators to judge whether an answer is orthodox or not. This is to be judged by the community using votes.
