Bot that will like comments?

Is there an automation tool that will automatically like a particular user's comments?

I am in a niche that has a few accounts that get around 20,000 likes per photo and 200-300 comments. The top comment often only has 2-3 likes. I am thinking that if I create a few child accounts to like comments I manually make using my main account, I will be able to be pretty near the top comment and get more profile views. I could manually like the comments but I'd prefer to just write the comment and have the automation like them.

My main account is at 117k and growing at 2k/week with no automation and I'd prefer to put all the risk into the child accounts - Hence this strategy.

As far as I know Jarvee does this

I'd say Jarvee.
I use MassPlanner and it does exactly what you are asking for.
