You can read/DL content for free on dlsite (any book on dlsite under 300yen) if you're willing to do some slightly tedious stuff:

>Start an incognito tab
>Create a new disposable email using one of these eg. https://temp-mail.org/en/
>Using the 'translate page' option on google chrome you can create a yahoo japan account (yahoo japan is rather diff compared to the gimped western version of yahoo we have)
>Here is the link for the above step (use the disposable email to receive the code) https://account.edit.yahoo.co.jp/signup?default_mode=mail&.done=https://www.yahoo.co.jp/

>You dont even need to remember the account credentials for the new yahoo account you created
>Now in the same window open dlsite and add the books, asmr audio, cg art etc into your purchase cart such that total is less than 300Yen (this admittedly gets you the less in demand stuff so mostly you'll get yaoi or old work)
>Click on the 300 yen off coupon on the purchase cart content, it'll ask you to register click register with yahoo (I chose yahoo bc its the easiest to create multiple accounts with, the other options are gmail, amazon, line and mixi - IF you know EASIER methods for creating multple accts using these pls share)
>After registering you can apply the coupon and get your stuff for free

My only request is if you get something good please share it on e-hentai. I found this method pretty much on my own as I am a poor coomer student whose credcard doesnt work on jap websites, curse Discover
Please do correct me if you know a better method.
