Account created in 2018 with only 9 posts and zero merit making such comments seems to be weird giving advices to all other members when he/she has not implemented it.It seems like someone just woke and plan to write in hope to get some merits through all these advices but it would work good if you first focus on learning and enhancing your knowledge.
In my country you get something like "e shock you (are you surprised?)". It should be like you seeing such for the first time in this Forum. For someone who has 9 post like you pointed out only signify that this user has been here for long, and he's just using this new account to start up something new, if not how did he know we all have to do these things he mentioned? These advise he gave are just ok but can it be put to use by many? Some of these new members really need to read this post by the OP and try to utilize it.
