If someone did not solve a kata, they cannot read your message anyway. Spoilers cannot be read without completing the kata,and this makes your "suggestion" mostly useless.

The meaning of the suggestion label is documented (for example here: https://docs.codewars.com/community#kata-discourse) and as you can hopefully see, the label is meant to be used for kata suggestions, and not solution suggestions. It is in general recommended to refrain from posting spoilers and solution suggestions of any kind, unless answering a specific question. Users who have problems solving a kata can post questions (and use question label for that), or even better, they can ask for help on CW Discord.

I don't think you're right. Many people here in chat writes about that and telling other people how to solve the problem. I uses a SPOILER button to indicate that my message contains revealed solution. If someone's trying to solve the problem and open the chat, it means he doesn't know how to do that and needs help. When he sees that my message is marked by a SPOILER button and he reads it anyway, that is not my problem. I solved it on my own and wanted to help someone, so this is my SUGGESTION.

You are telling people how to solve the kata, but you shouldn't do that. You should let people solve it on their own. A suggestion is meant to be an idea to improve the kata itself. What you are doing is spoiling the solution, so it is not a valid suggestion.

I mean that posts labelled as suggestion are meant to be used to suggest improvements or changes to a kata or tests. Suggestions should not be used to give hints about solutions. In general, hints about solutions are treated as spoilers and should not be posted at all, and definitely not labeled as suggestion.

What are you talking about? Please explain your point, I really don't understand what you mean.

It is not a valid kata suggestion. Additionally, it is a spoiler.

So is your suggestion to improve the kata ^^

An issue is a bug or problem with the kata. This is not an issue.

suggestions are meant to propose improvements to a kata, not spoil the solution for other users
