1. Is there a minimum/maximum limit we can assign as number of characters needed in a post a 'reply" to get published?(i have seen it for topics and post description). Image below.

The min post length site setting should work here.

2. Is there a mechanism in the platform to identify the hyperlink to be promotional, spam, advertisements, paid subscriptions etc.?
