Anthropic has plans such as $150/user and $150/5-users-but-less-hours-per-user. I could not work out what 2 users or heavy-usage-5-users are intended to do.

There are people that will always try to steal, but there may also be those that just don't understand their pricing.

Also some people keep going forever in the same session, causing it to max out - since the whole history is sent in every request. Some prompting about things like that (your thread has gotten long..) would probably save quite a bit of usage and prevent innocent users from getting locked out for a week.
