Hello everyone! Let´s block porn

Hello community! I´m a 18 years old newbie. Last night I pmo´d from 10:00pm until 3:30 am. I´ve regretted every second of it and I started searching ways to block porn on my computer from 3:30am until 5:30am.I finally found ways to do so. I hope that my information is useful for you.
There are lots of things you can do to block porn but since I didn´t find a way of doing so without a programme, I´m putting here some tips that have helped me and will make me abstain from porn as long as I use my computer.
I want to share some insight before I share what I did:

1- I didn´t find a way to block porn forever on my computer just like a guy in a NoFap thread did with K9 Web Protection app
The app K9 Web Protection was sold to Symantec and now we can´t use it properly without using third party websites and It can´t hold the job it was supposed to do because it is outdated in those sources.

2- With this problem in mind and knowing that just like me, you might have an antivirus whose parent control option doesn´t work properly or perhaps you are not able to afford an antivirus like Kaspersky that has a great "Safe Kids" app which is basically a parent control app in witch you can block pornography websites, I found this methods to be rather helpful.

3- You might already know some of this methods or even all of them since they´re available all over the internet. The trick is not in having different methods but rather in combining them in a way that your brain will think: "Nahh. If I want to watch porn I will have a huge amount of work ahead and then I´ll have even more work in order to return my previous options to block porn"

Let´s start:
1- You can change your DNS to OpenDns. Find out how in OpenDns´s website.
For this step I recommend that you do it both on your computer´s DNS and especially in your router. You must seek in your router´s provider website how can you turn the DNS into another since routers configuration settings vary a lot depending on the manufacturer.

2- Change your host file. Host files are used to resolve hosts names before DNS. Hosts files aide the network name resolution.You can learn how at github. Search for this matte on google and it will suddenly appear

3- This step could be dangerous but you´re the one who chooses what to do. You probably did a backup for your host file... if you wanna make sure you won´t go back and replace it in and on you can make your work harder by deleting the original.I think it would be quite easy to return this process, anyway,. However, the typical user only uses the computer to browse. It should not be a problem for most of you once the original host file is deleted.

4- I didn´t do this step because removing extensions (also known as Add-ons) in web browsers is too easy but if you want to increase the likelyhood that you´ll be lazy follow this step. Download an Add-on into your browser that blocks porn. I recommend Adult Blocker.
After installing the add-on whether you use Firefox or Vivaldi you can personalise the browser and hide the extension in the overflow menu (at least this works on Firefox which is the browser I use I don´t know what about chrome though). Notice that by moving the extension into the overflow menu you´ll be less aware of the extension and thus you´ll think less about porn plus it will be slightly more drowsy for you to
uninstall that Add-on.

The work´s finished. You can finally breath again! Yay!
I really hope that I´ve helped some of you guys and if not at least you probably have learned something.

Side notes: 1- I could not upload links nor images because I´m new here.I´ll change that when I gather the minimum requirements.

2-Please keep in mind that I might have committed either spelling or grammar mistakes since English is not my native language. I´d appreciate if you guys could correct me if you see any error in those areas. Feel free to do so

Bye!
