yes of course, but you must not spam, and wrong comments, your comments must be in accordance with the topic you reply to later,
like
-For example: Writing the same message over and over again. thanks, thx -and so on!
-Do not copy and copy other people's messages.
-Do not send messages to increase the number of comments in threads that you do not know.
-Write your own opinion when commenting!
Hope it is useful
