AryaM is seeking help with two tasks: blocking certain words from being posted and adding custom buttons to the screen, similar to a “community guidelines” button. Lilly provides guidance on blocking words by using the admin-customize-watched words feature and suggests creating a theme component for custom buttons. Canapin offers additional assistance, including a tutorial link and a step-by-step guide on creating a theme component with custom buttons, providing example code for HTML and CSS. AryaM expresses gratitude for the helpful advice from Lilly and Canapin.
can someone help me with these two things?
hi @AryaM 
for this you can go to admin-customize-watched words and use Block or Censor.
to do this you will likely need to create a theme component, depending on what you want the custom buttons or links to do. if you are more specific, perhaps we can help. Or you can post in Marketplace if you are looking for someone to do this work for you.
i hope this helps 
There’s a learning curve on how to do that, but once you’re done, it will be of great help.
To make it short, the part from the tutorial about Discourse modification that is about what you want to achieve is here: https://meta.discourse.org/t/beginners-guide-to-developing-discourse-themes/93648#modifying-discourse-templates-22
If you want to have a ready-to-use skeleton, here’s what to do.
Create a new empty theme component from Admin → Customize → Themes (don’t forget to enable it in your theme(s), or select your current theme.
Go to Edit CSS/HTML.
In Head, paste this code:
<script type="text/x-handlebars" data-template-name="/connectors/above-main-container/custom-buttons">
<div class="wrap">
<div class="custom-buttons">
<a href="/faq">Community guidelines</a> | <a href="#">Contact Moderator</a>
</div>
</div>
</script>
.custom-buttons {
margin: 1em 0;
text-align: right;
}
The result will look like this:
