We need a service to check any instance an account follows or is followed by, if this instance blocked all known (DB needed) Gab accounts. If not to notify the instance admin and checking again 5 days later. If the result is still the same then automatically blocking this instance and adding it to the DB that others check for instances not blocking Gab... and so on. After 3 weeks all Gab and not-blocking-Gab-Instances would be known and isolated. #IsolateGab
Still we would need an open and community driven database of those servers, voting end elaborating system etc.
