Unlike domain names where people actually pay for them, I think package repositories like npm should punish squatting like GitHub.

For example I contacted GitHub because I wanted an organization name for a company I'm registering in 2017. Their support looked at the organization, which had zero public or private repositories, told me they went beyond a time period of zero activity in which their name could be reclaimed by someone else and I got it (and no they didn't tell me the time period, it was just a vague statement regarding it).

NPM should look at these and if they've been empty for X amount of time, remove them. Now the problem is controlling new squatters so they may need to offer a more complex solution when a name returns to the pool but I think it needs to be done (I know names don't typically return to be re-used in NPM but if they're removing them for squatting I think they should).
