I was pointing out the repeated, predictable tactic of mischaracterizing the makeup of a group in order to have readers take what they write less seriously and be less likely to engage with the discussions.

As for what you said, I think shills try hard to respond quickly in order to get views and let their vote brigades have a greater effect on which comments are near the top while people are still reading. That said, there are also reasons why a shill would wait a while:

1. to appear like an actual human, so having a consistent pattern as if being a person living in a particular time zone, having an actual life and not looking too much like a full-time worker,

2. to wait for central leadership to think things through and refine the narrative and game plan,

3. to post at a time when the bulk of the forum participants will see their (artificially upvoted) content and

4. to reduce the chances that anyone will still care enough to respond with a rebuttal.
