Don’t overthink it. I bend the rules in my communities quite often. The case that happens most often is somebody posting a duplicate of a news story. However, it is usually one or more days later and the new post usually picks up some comments from new people that didn’t comment on the previous post. I often let those slide. As long as people are trying to constructively engage in the community, then I give people the benefit of the doubt.
I work in pharma, regularly writing and filing things with the FDA (and other agencies), and this has been a topic of conversation at work. The good news for people is that the EMA is still a thing in the EU. So, at least the large pharma companies (like the one I work for), are likely to not really change much about their quality control/processes/etc. because we will still need to conform to the EMA guidelines which are typically in line with the current FDA (sometimes more strict, sometimes less so). The real quality concern would be smaller companies that only file for products in the US. They would only need to meet whatever new FDA guidelines come into effect (if they even do, changing stuff like GMP guidance is extremely complicated and time consuming) since the US is their only market.
