It's pretty extreme to insinuate that users are bots with no evidence. I checked both users' accounts and find it incredibly unlikely that either is a bot.

shmerl, the user who mentioned mynoise in that link, has 11,234 karma and has had their account since 2011. rob74, the user you're responding to, has 5,923 karma and has had their account since 2016. Both are recently-active users with a history of real comments that don't mention mynoise.

Perhaps you are seeing this site mentioned frequently because users enjoy it and it fills its niche incredibly well. I previously came across it searching for a Shepherd tone generator and have found that it offers the best balance between tweakability and ease-of-use.

Dude. The site is great, and people mention it from sheer good will.

Someone asked if anyone knew how to make a certain noise and another user replied with a solution. How is that not relevant?

The specific link is to a data centre noise field, which seems more relevant than not if someone is asking for software generated HDD clicks.
