Edit: Also, Do we suffer from bots? I never saw them. There was a bot assault on the smaller forum I inhabited before, Is it a problem with all forums?
Without tempting fate, as already mentioned there are odd commercial-linkers[1] that I have noticed and reported and (SFAICT) got quickly nuked by someone or other up to and including the Prime Toad themselves. I have no doubt there are many more instances that someone else noted so much earlier that I didn't even get the chance to see them.
I once had a very basic web-board go very bad with recurring bot-spam (basically concerted SEO-linking rubbish for fringe web areas, it was in days without even much of a CAPTCHA capability by default and once identified as an 'open' board by various site-databases was very receptive to a recurring spam-effort by any script-kiddie who could be bothered. Eventually had to be closed to posting, and never did get completely cleaned of all rogue messages (which should have left just the ones related to Darwinian Poetry, which was the site's purpose, ironically). The whole site vanished (the last residual domain/server fees obviously expired for whatever reason) a number of years ago, or I'd show you. The real regular posters were generally a very good community (insofar as you could keep track of individuals) but the tsunami of gunk just sank the legitimate chatter entirely by the end of its postable era.
Things have changed a lot since then, though, and even an SMF forum is itself a little long in the tooth. Next-next-gen web-accessible meeting places are being overtaken by ever-more-proprietry App-based E2E-encrypting multimedia-embedding datastream-enncapsulators that challenge both spammers and their maintainers in many additionally important ways. Luckily, also as mentioned, traffic and attention to traffic seems not to be so badly out of balance (whilst still being useful) and if DF itself does not suffer unavoidable inactivity (or become the Next Big Thing or 'suddenly' an Overnight Success, perhaps from the first proper Steam Release, in a dissapointingly Rowling-rather-than-Pratchett hyped up way) then there seems no reason why Bay12Forums should not continue to consistently shadow Bay12Games.
....well, that's all my opinion. I never thought LinkedIn was worth using, though, and have consistently resisted Twitter/Facebook/etc as (at first) fly-by-night fads and (later) all-too-popular platforms that it isn't worth belatedly trying to ingratiate myself into the culture of. So you might consider my experiences and attitudes a bit too misaligned to your idea of reality.
[1] Without giving away all the the ways to avoid near-instant detection: posting something equating to "Yes, that's a good point!" with some random words linking to url.spamsite.ch/h3X4D3C1M4L?reference, necroing a three-year-idle thread that I had participated in, could well lead to some well-established Bay Watcher like me to call in the appropriate level of the Moderation Cavalry... And when you check the poster's account, they had just made three posts of similar nature[2], which get either further reports from me or a nod to them in the original report-field.
[2] Maybe a less obvious and apparently blameless 'test' post a week or two ago if they thought they were playing the 'long game', which probably indicates that such individuals[3] have a very widespread 'territory' of target sites to try to infiltrate, prod, test and then ramp up their campaign upon. Either that or they don't really have much time, in-between doing their day-job, getting visiting rights with their estranged children every weekend and rebuilding their fire-damaged kitchenette.
[3] Though it's probably an old-hat inroad, I recall that when last I was thoroughly looking through job adverts (early 2000s) as mandated by the Job Centre (while I was really looking for my next job in industry-specific places that didn't tend to include badly re-re-re-scraped text elements such as "—", and knew the difference between # and £ symbols) I'd occasionally come across an advertised job or two whose purpose was to "post to websites such messages as directed", which I'd print out just to point out to the disinterested (and uninterested) jobcentre person that it was probably not a particularly useful job to advertise. Though that was before the days of any real knowledge about Zero-Hours Contracts being notoriously worse.
