Considered to off-topic: YES
We just have considered it to be a habit when someone make an application to a CFNP Campaigns, but overall it's an off-topic reply. Looking back at the thread there are also some replies that are considered to be off-topic but it wasn't deleted, maybe it wasn't reported to the mods and yours was actually has.
There are round when pages of off-topic discussion posts were splited and moved to another thread, in Reputation or Service Discussion. But if there are not many posts like those, moderators will delete them rather than split and move them.
