I’m getting annoyed with people that ask a question, have the community answer their question and troubleshoot over several days, only to delete their post and the solution.
The person asking the question is often providing the least amount of effort, so why should they have exclusive right to delete the contributions of others?
Possible fix: have a per-community option to only request deletion.
Moderation is even more difficult when you are just a person hosting one node in the federated platform. Each node needs to take an active role. And as the volume of content/users goes up, the workload increases.
Moderation is a huge part of running any platform. Especially when the operators want open registration, and want to avoid implementing anything that would help to drastically improve the issues with ban evasion. (The strongest solutions are problematic.)
