Hi, head of community at Sourcegraph here. We don't use bots. u/Prolacticus is a Pro user, we do not pay him/her, and they are not sponsored. In fact, I offered them swag a month ago, and they refused.
We do give free/sponsored accounts to our Discord mods, open source maintainers, and folks who write guest blog posts for us. u/Prolacticus is not one of those accounts.
I fully believe that you aren't paying him directly to do this, but I don't believe that any human would shill so hard (and always mentioning the price and the same gist of 'it's fantastic' etc). Any chance it's a replyguy or similar test, either by someone else in your org without your knowledge or just by the creator themselves as I guess they need to do some 'live testing' before charging real 'customers'.
