One thing that's nearly impossible to appreciate about social media platforms, even
small ones, is their
scale. Both in terms of users and content.
FB see about 5 billion items posted daily. Or about 58,000 per second Most of those simply die unread. Our Internet has become a write once, read never medium...
If an item is to be picked up by amplification algorithms, it needs some indicia of relevance or significance. Broadly, that comes from one of 3 propeties:
- Content itself. Keywords, hashtags, URLs, other profiles linked.
- Social graph. Followers and readers of the submitting account, and their own followers.
- Engagements and interactions. Any likes, comments, or re-shares, with their own attributes as well (content, social graph, engagement.
Given that signal for a naked submission is so thin, any indication of additional relevance is likely glommed on to, and a set of rapid initial engagements might be a sign of high-value content ... or of a bad-faith mutual-admiration-society cabal (MASC). Even on sites such as HN, a little early engagement on a submission goes a long way.
Note that a group of freinds engaging with one another's content will look a lot like a MASC, though in most cases the significant distinction will be posting volume. It's rare for a person to consistently post more than 10--30 items a day, and much above that tends to get seen as annoyingly verbose by others. Promotion and amplification accounts can post many tens, hundreds, or thousands of items, hoping one will take off. Their goal isn't engagement but manipulation, they have cheap content-creation processes (stock bits, redistributed content from other sites, randomly-generated crud), and can afford to be profligate. Until the system actively penalises based on submissions without significant uptake, that's going to be the case.
Why this is happening is anyone's guess, though in general, cultivating a capitive audience has value, whether for conventional advertising or propagandistic purposes. It may be that the accounts are intended for direct use or will be farmed off to other buyers or uses later.
Gaining profiling information on follower demographics and influence points would also be part of this.
Given political cycles, odds that this is prepatory for the US 2020 campaign seems a plausible explanation.
