Definitely had some months with spiked growth. However they never accounted for more than maybe 10% of subscriber count. My growth has always been steady and consistent.

I don't sell a "course" either.

A YouTube Accelerator Program is a real thing. Just alike any other accelerator for other niches of work. The intent is to accelerate the growth of other's channel via analytical reflection, application of SEO etc.

Nothing I do is a scam, in fact my company offers a money-back guarantee to all members that don't end up with satisfactory results.

Also, nothing was an advertisement? I specifically stated I was not going to say my channel name or company name for that very reason. However, you decided to go digging for my company and putting it on here.
