I have a hidden service but... : HiddenService | Torhoo darknet markets
I have built a tor hidden service that can host blogs easily with Javascript being strongly discouraged and every blog is very customizable and there is basic filtering on the site for bots but overall very easy and simple to make a blog on the site but I need help hosting it as I cannot sustainably afford to use my personal devices so could someone tell me how I can host my onion site without some sketchy onion hosting provider reading my source code and or leaking it.
Also I do not have any money sadly for this idea so any support would be helpful
You should not be using personal devices to host it because this only ends badly. I assume you are hosting it locally now which is okay for testing but not ideal for production.
Any hosting provider you use will technically have access to your source code because they own the servers. Do not using onion hosting providers, find providers who are normal. You can exchange monero or bitcoin to prepaid visa/mastercard and usually pay with those.
