Let us go point by point.
>I still recommend you ttf tag
Please no longer make suggestions to monogram, or any other project of mine here on itch.
>you wrote CC0 on the second line (...) License info usually (95% as it seems to me) in the end of the page
As I said, the info was also on the metadata, which is ALWAYS in the "More information" section at the end of any project page. To make this mistake, you'd have to fail both to read literally 9 words into this page, and to check the metadata you are supposedly concerned about, at the end of the page where you claim it would be easier to find.
>Do you think it is better not to do it at all?
No idea what is "better". I find your comments rude and unhelpful, and you provide no context for your demands. Why would the "ttf" tag be beneficial? What discoverability or accessibility issues would I avoid by using that, in comparison with the "fonts" tag, which has over 6x as many entries? You never said. You just dropped into the page of an asset you have no interest in using (or even reading the description) and made a demand. Please stop.
>If you don't like my actions and comments, you can report me as spammer
I will not report you as a spammer at this moment, but what you are doing is definitely spam, and it would not surprise me if other people did report you.
I believe your push for UI improvements that make metadata settings more visible, or incentivizes creators to add them, is a good idea. But if you insist on taking this crusade into your own hands, you absolutely should work on your tone and do the minimal due diligence of checking the metadata of an asset before commenting.
