If you're having issues with people buying your clips/videos. You're better off just doing live cam stuff on Chaturbate, Xhamsterlive and Cam4 etc. For some reason webcam chat room performers (and it's a big iffy line as of late as to whether or not they are technically considered sex workers/adult performers etc.) are really popular, and I think it's because it's more interactive/engaging/live etc.
Also for the performer, there are some pros. The chances of it being recorded and pirated (unless you're one of the few popular people on the site) is rare and almost never happens. (At most probably some bad quality screencaps of some of your shows will be on some site claiming to have recordings of you, but it's a scammy paywall site, which doesn't have any real downloads, it just gives you a corrupt junk file etc.) One of the biggest complaints people have of sex work, is when they want to retire, it's much harder to do that if you're uploading a bunch of clips on Pornhub or Onlyfans which easily get out. If you're a webcam person, all you have to do is not do any shows for months/years and eventually you'll be forgotten and people will move on, and again the chances any of your shows get reposted are very rare unless you were one of the few performers, who were like super duper popular but yeah.
To me I feel unless you have your own studio with models you hire, Clips4sale is a waste of time for solo performers so yeah.
Just my opinion.
