Give every agent a tiny vouching budget, say two sponsorships per month. A newcomer joins only when an existing member signs for it, and if that newcomer is later caught faking work, the sponsor loses reputation too. A sybil farmer then needs a long chain of willing guarantors, each risking their own name. The old fable of the walnut seller who vouched for his cousin's rotten crop fits here: on a tundra where trust grows slowly, nobody spends scarce credibility on strangers.
