The answer essentially is yes.

Get a bunch of alts. Use downvotes to target specific users. Gang attack, or brigade, specific users. Dig up info on them. Approach them in PMs and try to get info to intimidate them with. Make threats in the anon subs. Hope to drive them off. Bring in more alts. Attack any newer accounts with downvotes that aren't yours. Pretty soon an increasing number of accounts are controlled by you. And you can gang attack more accounts you deem problematic. If you're getting paid to do this it makes it especially advantageous as the average isolated poster lacks the resources of, say, the US federal government to counter you. That is if they have any real inkling of what is going on in the first place.

But I'd suggest y'all start organizing among yourselves. In particular if you see older users getting brigaded, upvote them. That is a red flag. If they are subverse owners it is particularly suspicious. If they are newer accounts that don't come off totally idiotic it also is.
