The only solution is to limit each thread topic in Bitcoin Discussion up to 24 hours only (forum standard time), Because even if the topic is relevant/necessary the majority of it to be spammed is up to 100%.
The Orange tag will only indicate that you are a shitposter you're still labeled, and a lot of color tag will only confused the new member of this forum and it will be laborious, However if it will be implemented who cares?. The solution with the tagging is a sign petition in Meta 1 to 2 month review for doing something unnecessary in the eye of the DT.
