Let's assume all DT1 members were legendary users, can you just imagine the level of drama the forum will be recording on a daily base. No offense to the active (net positive legendary users of the forum) but from my observation, if there isn't a controversial accusation ongoing resulting to drama, hardly before you see any legendary users showing interest.
The lower ranked users (Hero below) are actually the ones doing a great job in trying to police the forum. You would observe that, if you spend some time on the scam accusation board. These guys spend timeless amount of hours researching on different projects, pointing out red flags like Plagiarism whitepaper, fake team etc then report with detailed info and evidence. They're also engaged in combatting other countless type of scams.
Most legendary users are feeling too relax and showing less concern towards the forum. Being a DT (most especially DT1) member should have everything to do with your level of commitment to the safety of the forum and not your rank status. We have some net positive legendary users but they're very few.
