What is Drip-feed?
Splitting one order into smaller runs delivered at intervals.
Drip-feed lets you deliver, say, 1,000 likes as 10 runs of 100, one run every 60 minutes. The total is the same, but growth looks gradual instead of instant.
On LikeAdda, services that support drip-feed show 'Runs' and 'Interval' fields on the order form.
