omiwoods review for Shopify Collabs

I haven't started using this yet but have a question. If influencers don't link their social media to this program, doesn't it mean that the only way for them to generate affiliate sales is through an affiliate link. Is this the reason for the link. This way they simply need to mention the @ of the store, and it still gets considered as a referral - a more natural one at that - rather than referrals only coming through via their unique link.
