| There really ought to be some general rule of account classification in a broad-based public service. My very rough rule of thumb: 10% of accounts are active (daily/weeekly participation) 1% of accounts are "whales" (provide high level to the service). ~15-50% of accounts are some-time users. ~25-50% of accounts are one-time users (registered but never used) If your service is sufficiently old, call it 5-10 years ... ~25-50% of accounts are expired / no longer reachable (usually the contact email/phone is no longer valid). Active spammers don't have to be a high level of the service to be disruptive, but can be anywhere from 1-25%, mostly depending on how effective you are at rooting them out. Very, very rough, and no, I don't have a particularly good basis to back these up other than the first 2-3 values. |
