The majority of my postings are NSFW. If you are under 18 or you do not feel comfortable looking at them you can take a piece of paper, fold or cut it into the appropriate size and hold it against the screen to cover the content. Or if you happen to be at work, stick a post-it onto the screen which would basically have the same effect. In these cases you would want to avoid uncontrolled scrolling. This would lead to rather unwanted consequences.
Otherwise simply enjoy the contents.
My policy is: what is online can or should be reposted. The internet never forgets and everything can be copied and pasted everywhere. The technical possibilities are there.
Never the less: If you are the rightful owner of the original content (which has to be proven first) and you do not wish to have it posted, then I will of course delete the mentioned post.
