I never really understood why that is
As our Rules say ' We do not allow images or videos which portray real life crux-play using nails,
or any content that encourages or assists such activity,
which is likely to cause serious, permanent injury or even death, and which could lead to criminal charges'
(in UK for example, no-one can be deemed to have consented to activity which causes them actual bodily harm)

Safe DIY cruxing I have posted here that I crucify myself in my own privacy. This can be very dangerous & the thought of getting into a position where itÃ¢â‚¬â„¢s impossible to escape is rather a nightmare. I thought IÃ¢â‚¬â„¢d share with any others who would want to do this the means I have...
My friends I have been a member of this forum for a long time now,and in the time we have heard from a lot of people who have expressed the desire to be crucified with nails and while they have that right to do so I must express my concern to them.You have the right to seek crucifixion with nails if that is really what you want,but be warned of the danger that comes with such a desire...I was crucified with nails when I was a teenager,the nails were driven into my hands and the pain was unlike anything I ever experenced in my life,I hung on the cross for 30 mins. and to say I suffered would be an understatement.I receved good care from a good doctor after my crucifixion and I recovered fully after about a month.But there have been after effects from my crux,to this day I suffer from arthritis in my right hand and also tendonitis,my left hand is ok so far and the scars are almost invisible now.The nails they used on me were small but they still caused damage to my hands that I will live with for the rest of my life.Please if you seek to be crucified I beg you to use rope and have people with you that you know and trust to keep it safe,please don't use nails it's not worth it and I should know...I was crucified for money when I was a young teen and I was stupid but I needed the money...but trust me when I tell you that using nails is dangerous and not worth the risk!If you really wish to be crucified please use rope and have a fun safe crux!
