Can I use BlockSurvey with multiple accounts?
BlockSurvey accounts are on a per-account basis. This means the Account ID / Account Username / Blockstack ID you use to login to BlockSurvey is tied to a subscription (if you’ve purchased one).
Today, each account takes a individual subscription in Personal plan. We don’t offer a way to purchase one subscription for multiple accounts for personal plans.
If you subscribe to them individually, yes, you'll be able to use them.
