We have recently throttled renter accounts for the purpose of eliminating ones that were gaming our network as well as filtering out inactive nodes. Since our V2 network is already deprecated for many months, we no longer will reactivate old accounts.
However, if you want to store data on the decentralized object storage network, then learn about Tardigrade, the enterprise, production-ready version of the Storj network, complete with guaranteed SLAs.
You can also already start testing our new V3 network here. Thank you for your understanding and patience while we work on getting the V3 network into production!
