Folks can be critical of comments that do not relate substantively to the post.
When you make a comment, be sure to discuss the content of the post, and then you will not be treated like a bot, or a spammer.
Since English is not your mother tongue, you may have to use a translate service, but it's a good idea to do so.
Also, there may be communities of folks that speak your language, and that may make engaging with them on their posts more constructive.
Good Luck!
