Why do social media managers need proxies?
Because platforms treat shared IPs as one actor. Agencies managing many client accounts from one connection risk linked suspensions where one account's problem takes down the rest. One dedicated IP per account (or small account group) isolates that risk.
IP consistency also matters for trust scoring: an account that logs in from the same city and ISP every day accumulates a normal-looking history, while one that jumps between datacenter ranges invites verification loops.
