hi @voltranrex firstly, thanks for your upvote, second secondly i hear what you said in the comment. Leaving feedback in the comment section can be tricky to know whether it is for real of attempted spam. To me, I take both the same as feedback.
If it is a spam, then at least I know my post can be found and get noticed. Obviously for some comments, it is not difficult to identity the writer;s sincerity especially they can pin point the exact fact in the post.
In anyway, to me there is no right or wrong but a matter of opinion
Once again, thanks for you comment and input
