Buzzoid is one of the older names in this trade and sticks close to Instagram. It sells followers, likes and views, split into instant and higher quality tiers. Likes packs start very cheap, and follower packs scale from a few hundred up to tens of thousands. Payment goes through card, and only the username is asked for.
Good for a person who wants a simple menu and steady delivery without setting up an account. The higher tier costs more but brings steadier numbers. Those who need TikTok, YouTube or a full campaign will outgrow it quickly, since the range stays narrow.
