Running more than a handful of accounts changes the risk profile of your operation entirely. A single mistake — shared IPs, identical activity timing, careless device reuse — can cascade into a dozen accounts being restricted in the same afternoon.
Never mix proxies across accounts
The single biggest cause of mass account restrictions is proxy or IP overlap. Platforms actively look for accounts sharing a network fingerprint and treat them as a linked cluster the moment one gets flagged. Keep every account on its own dedicated residential or mobile proxy, permanently.
Stagger activity, don't synchronize it
Accounts that post, log in, or take actions at identical intervals read as automated to most detection systems. Build natural variance into timing rather than running every account on the same schedule.
Treat replacement windows as a checkpoint, not a fallback
Verify every new account within its replacement warranty period rather than waiting until you actually need it in production. Catching a dead account on day one is a non-issue; catching it mid-campaign is a scramble.
Separate your operational identity from your accounts
Keep recovery emails, backup phone numbers, and device profiles distinct between operator identity and the accounts you manage on behalf of clients. This containment is what keeps one account's issue from becoming everyone's issue.
Isolation is cheaper to build in from day one than to retrofit after your first mass restriction.
None of this requires exotic tooling — just discipline about keeping every account's footprint genuinely separate from every other account's.
