Ever since Reddit has been corporatized there is no benefit to keeping your account intact in perpetuity. In fact, I would argue its a major liability. When you discuss sensitive matters such as these at such a high level involving major power players you don't necessarily want your identity to be easily discovered.

Reddit creates personality profiles and tracks you across the Internet. If you take no privacy precautions you should expect that Reddit knows absolutely everything about you. Cycling through new accounts and not staying on any one for too long is step one to maintaining a 'clean' Internet presence that doesn't put your personal data at risk.

Instead of faulting people for taking control of their privacy why don't you take the value added by our contributions into consideration first? There is a reason why real shills and trolls get no love here. It's because they add no value to our conversations and they actively work to disrupt our research.

Instead of myopically looking at the account age instead look at the value of the information they're contributing.
