The socials are a handy way to stay in touch with friends, find out about dancing events (if they’re ever allowed again) and to get information direct from experts. They’re also an unrelenting cesspool of trolls, bots and undesireables. What to do?
On my PC, FB Purity lets me filter on keyboards (I’ve chosen “trump” and “brexit”, as you can see). It can hide various types of update from your feed. I hide stuff like “Fred commented on this thing” (as FB friends sometimes like to argue with the undesirables), as well as adverts. You can also force the feed into chronological order rather than relying on Facebook’s algorithm to show you what it thinks you should see.
On my phone, I use Friendly for Facebook, which isn’t quite as good but does have the keyword filtering (“commented on” works as a filter) and, if you give them a donation, will also filter the adverts.
Tweak New Twitter gets rid of a lot of noise (like the “Trending” stuff and sponsored tweets). It can put retweets on separate page too. To use it on mobile, you’d need a mobile browser which lets you run extensions, Chrome on Android doesn’t.
Twitter has keyword filtering built in.
Secateur blocks people and optionally all their followers, unless you’re following them too. It’s adding to your Twitter blocklist, so once people are blocked, they’re blocked however you view Twitter. I guess there’s a risk that some decent people are following undesirables to keep an eye on them, but if it catches on, I can imagine people using separate accounts for that (of course, the undesirables can do the same trick, having one account for trolling and one for following, but they don’t seem to be yet). It wouldn’t be that hard to extend Tweak New Twitter to add a “Secateur” button to Twitter, either, I might look into that.
The next stage on from this, especially if the undesirables maintain accounts where they don’t follow other undesirables, would be the web of trust: only show replies from people you follow, people they follow, people the original tweeter follows, say.
