Telling someone they re-steemed their post really isn't something we deal with. While this is obvoiusly a comment left by a person it still falls into the category of 'community service bot' as they are announcing they did something they perceive as good for the community.
If you disagree and don't find value in this type of comment or service, flag it. As a member of @steemcleaners I don't want to be in the position to decide whether or not a service is valuable to the community. That is something only members of the community should decide.
Flagging & upvoting these comments provide feedback on how the community feels about the service they provide. Whether it is a project that has been formally announced or just someone thinking they are doing a good deed and announcing it.
I see they stopped asking for user to check their profiles. I'll keep an eye on it.
