Here are some basic bits of information that may be of use to you…
In order to reduce the amount of spam that can come from automated bots, new blog posts will only remain open for comments for 7 days. At the end of which, the comment section will be closed and will not be accepting any new comments.
Additionally, in order to comment on an open blog post, you will be required to submit your name and email address, along with your comment. Failure to submit the required information, your comment will automatically be removed/deleted. Please note that the information you provide will only be used for verification purposes and nothing else.
Finally, before your comment will be visible, it has to be verified by the blog administrator. This is the final step in verification and to fight spam.
