As a general principle, if your goal is to increase safety
* Bigger accounts are less likely to need to be blocked.
* Older accounts are less likely to need to be blocked.
* More passive accounts are less likely to need to be blocked.
But most blocklists aren't run this way and consensus blocklists exacerbate this situation.
Those will tend to focus on older accounts. They will tend to focus on bigger accounts. Their detection of passive accounts will go up over time.
This doesn't help.
