This is a nice thread and I hope the admins have checked the stats themselves. Those Alexa figures showing decrease in traffic here might be because crypto is not that much popular as it was when bitcoins peaked at $20000. However, mods have additional tools to check the activity like time spent by users and all, total posts being made.
In case, the forum is suffering because of the rule, it should be modified. Admin should be flexible enough to do so if he wants this forum to continue for long.
