/vt/ - Virtual Youtubers

Everyone always says to buy an ad but realistically speaking how effective are ads for vtubers? Do we have any proven cases where purchasing an ad seemed to have increased a vtubers overall public visibility besides the artificial ad count? Is it better to buy an ad, view bot, or create drama? For view botting there has been incidents where people gain short time relevance for little pay but higher risk with the chance of a ban, and for creating drama you could cite the case where veibae tried to create drama with Shylily saying she copied her voice but that ended up profiting Shylily in both the short and long run because veibae sounded like a schizo.
