Porn Hub, your website's social features are a dumpster fire. It's not even hard stuff to fix,you're just that lazy, incompetent, and apathetic.

Easy & Free PC program to download hard copies of videos for backup:
I'm not shilling or in any way affiliated, I just know how disappointing and frustrating it is when one of your favourite videos suddenly disappears without any trace or warning. And I also know -vividly, as I just went through this struggle- how laborious, potentialy risky and probably futile it is to search for a method of downloading videos with no strings attached.
But after a long search with many failures, I'm elated to say I finally found an excellent solution!

Considering the effort I put into research and testing, and how excellent the solution I found is, I'm happy to point anyone else who's interested in the right direction. But I'm rather hesitant to post it publicly, in case I draw the wrath of PH. I'm not totally comfortable even posting this, as it could potentially be misinterpreted by an over-zealous moderator, but hey sometimes you've just gotta take a chance when you're passionate, and put yourself on the line to help others!
So anyway, hit me up if you're interested and I'll happily share what I've found. Preferably send me a message or write here on my wall and I'll fill you in.

Strange that my stream hasn't updated with any of the videos I've favorited or added to playlists over the past month. I've definitely added at least a handful recently. So frustrating that even the features they do implement seem to be more broken than working. But I'm stuck here as they've got the widest selection of quality pegging videos that I've found. Oh, the power women have over me!

'Incápacitated' (I had to use some accented letters as spelling it with all regular characters would have blocked me from posting) After much trial and error (because OF COURSE they don't tell you where the problem is), I found one offending word. The rest of the snags seem to have indeed been caused by the filter spazzing out on formatting or who knows maybe it didn't like the colour of my socks.  I did find a few clues into the assbackward principles behind PornHub's terrible language filter. That word at the top will trigger the filter, but I can for example say: 'tied up', 'restrained' 'unresponsive, 'smashed', ', and 'out cold'. So I suspect the filtered words aren't selected based on their meanings, instead the goal is to outlaw words which are used by people trying to share and find content which goes against ToS (or even just interests which are 'potentially problematic'). So that word at the top probably joined the filter list because it was frequently used to identify stuff involving lack of consent, substances, or people 'not awake' That makes a little more sense than if the words themselves were being considered offensive, but that approach is still ridiculous because the content and those who seek it aren't being removed. People VERY quickly adapt and improve. They will (or already have) started using language which is indistinguishable from the regular content to outsiders and AIs. They can use misspellings or word order to code dogwhistles for those who are interested, but are totally innocent to everyone else. It's ALMOST like poorly implemented security has negligible impact on the intended targets, and actually only serves to frustrate and annoy genuine users who follow the rules! Why is it that a literal Wanker know this stuff,  but apparently one of the world's biggest websites hasn't quite caught up to the security standards of the 90's?!

THAT'S what offends your delicate sensibilities, PH?!?! C'mon, saunter on down from your ivory tower and take a look around at what lurks on the ground level of your positive well-being paradise. I don't mean to alarm you, but if you do a little digging into the proclivities of your user base, you might find that a rather unsavoury element has infiltrated your community of respectable church-going PTA members. I've even heard rumours that some of them might be posting......... *sexually* explicit content! Quickly Porn Hub, you must make haste to the bead-clutching chair, lest the shocking deeds of these dastardly ne'er-do-wells corrupt you!

P.S. - Had to spend ages editing my previous post, then this very paragraph, many times, because PH has a hyper-active "banned words" filter. At this point I suspect it's taken issue with some formatting, because clearly they haven't yet aquired the skills and technology to tackle that advanced feature of  *text entry* (ok I REALLY don't have time to start ranting about their many other UI fails). I've removed everything that I thought might even remotely be "problematic" - for a PORNOGRAPHY website, lets remember. This isn't a Gender Theory class at Little Lord Fauntleroy's School for Albino Hemophiliacs.... or did I come to the wrong website (again)?! Provided this is PH, we shouldn't need so much concern for a "safe space" should we, really. Like, My god, the things I've fap....  I mean, things I've seen that deeply disturbed me (probably still true), hosted on this website, plenty of them still around post-purge, but we're ultra concerned about sanitzing problematic language.
