Although marketing agencies might get a temporary rise in "social proof, " buying LinkedIn followers is, at the end of the day, a net negative strategy. The followers are basically bots or dormant accounts that do not give any engagement, thus are a negative signal to the LinkedIn algorithm, telling it that your content is of low quality, and it is therefore greatly limiting your organic reach. Besides, savvy B2B clients can easily see the mismatch between a huge follower count and low post interaction, thus the agency's credibility that the purchase aimed to establish is destroyed. Most of all, it is a breach of LinkedIn's terms of service, and therefore, the account is very likely to get shadowbanned or suspended permanently.
