It seems like a relatively interesting idea, but it's only really useful for people who have done something wrong (which resulted in them getting banned), so I'm not that sure about it.

As for the code itself, it doesn't seem like much work, is very simple, and even with its simplicity, the quality of the code is still quite poor. Some things you could improve:

  • Add some validation to the form. Only certain characters can be used in a username, can only be of a certain length etc. - you should take this into account.
  • The identation, or lack of identation, just makes the code hard to read. You can install a linter if you really can't be bothered to do it yourself.
  • Comments like echo $total; //print total blacklisted database aren't really necessary. Comments should be used to explain code that is difficult to understand.

I would also recommend you link the relevant commits and / or PRs in the body of your post, so we know what is part of the contribution (I used this commit). Good luck with future contributions, I am sure you can use this feedback to improve!

Hi @nawab69,

Thanks for this contribution. I was excited to review it but, after looking at our questionnaire, I drew the conclusion that your post is better suited to be reviewed under development which I hope will get you a more favorable score for your efforts.

At this point, I would advise moving development to the second tag and maybe switching antiabuse with the abuse tag to ensure that category clears out of the system.

One observation on the checker is the case sensitivity. You may want to modify the related line to convert the string to all lowercase or something to that effect.

I've noticed you have taken the feedback given you from @justyy in the linked update so that is good to see.

Tagging @amosbastian for his awareness. He does the bot code so he will be able to clarify how we need to proceed if I had misspoke.

Thanks again!
