You can find an example of such operations here:

Last summer, after Old Joe Biden was forced out of running for reelection and Kamala Harris was anointed as the Democrat candidate for president, the far left’s propaganda arm (that is, the establishment media) made a massive push to make this failed vice president and longtime party hack seem new and appealing. A key part of this effort was a gaggle of young “influencers” who took to Instagram and TikTok with an enthusiastic pro-Harris message. It was sincere, it was spontaneous, it was exciting — or at least that’s what it seemed to be. Now (I know, knock me over with a feather) it turns out that the whole thing was faked: the entire Harris bubble was the artificial creation of a bunch of leftist billionaires.
