Pipelines build user account changed

We used to have an account that did all of our commits in Pipelines. As of today the username of the commits triggered by pipelines has changed to commits-noreply[at]bitbucket.org, this causes all of our builds to spiral into an infinite loop, since we check for our good old build agent username to determine whether or not to run the build script and release a new version.

Is this an intentional change or have we messed something up? I have searched everywhere for a setting, but so far I have come up empty handed.
