In the case of youtube, there are 2 ways you getting paid can be paused. In the case of, for instance, a copyright claim, your video will either be taken down completely or, if left up, will typically still be monetized with the money going into escrow until the copyright claim is resolved, with the winning party getting paid. The 2nd kind is this kind, where they deem your video isn't monetizable. Likely they think their advertisers would be upset to have their advertisers next to you or your content. In this case they just don't run any adds at all, so there is no money for you to be given if the monetization is resumed.
