Downvoted>>107853> >Reddit /r/painal> Other subreddits which obviously violate Reddit's policy* regarding violent content yet strangely still [as of 2023/05/15] persist nonetheless: /r/Roughanal /r/DegradingHoles /r/analfisting
On a more serious note, /r/analfisting was banned recently — NOT due to being in violation of Reddit's policy on violent content, but rather "due to being unmoderated."
As noted in the "fi" (fecal incontinence) paste in the OP image: "Stretching the anal canal with girthy insertions is likely to disrupt or fragment one or both anal sphincter muscles, possibly without pain as the internal anal sphincter muscle also lacks somatic innervation. Such damage results in permanent muscle weakening and is associated with FI especially with a damaged or dysfunctional puborectalis muscle. Stretching the anal canal repeatedly with insertions of progressively increasing circumference may cause cumulative muscle damage."
There are many studies included in the references compilation (comprised of T&A, A&T, AR1-3, and P&I) pointing out that anal dilatation/stretching is likely to permanently damage one or both anal sphincter muscles at the least. This is because it used to be an accepted treatment for anal fissure, but has fallen out of favor due to unacceptably high rates of fecal incontinence owing to muscular damage demonstrated by anal endosonography.
Anal fisting undeniably constitutes violence (i.e., injurious behavior) for any receptive person with intact anal sphincter muscles.
