Lately I have been receiving a lot of comment on my WordPress site.
And must of em seems odd with some Chinese images but their names and email look okay.
The comments are almost similar and looks this:

"Thank you - with valuable information".

I do edit most of them to be more reasonable before approval.
The question is: am I making a mistake approving them after edit? or should I delete them?.
Note: my website is New (3 months)

please don't read and go. I need an answer concerning this.

Don't approve them.

Don't approve them.

I have already approved some... should I delete them?

First the comments are spam. I hope you know what spams mean. The first wrong you did was to approve them. And I want to emphasize here that most of the time, spam comments does not necessarily mean someone somewhere is checking out your site and typing in the spam comments. It can be from some plugins you installed that has been doctored by hackers with spambots.
The first thing you need to do is check yourself.
Was there any third party plugin you are using that was not from the original WordPress plugin page?
Also you should know this, if a spam bot can filter through the security walls of your site. An hacker can have access to it through that same crack. The more reason why you shouldn't ignore them but do something.
Solution: research on some very good anti spam plugins... (I think I'll suggest Akismat) set it up and see if it stops.
If not, identify the plugin that is bad and deactivate it.

Let me know if this helps

Actually the comments are coming from only two articles I wrote on WordPress books and web hosting services. I do add source links for the WordPress books and the hosting services on the article. I am suspecting that's where the Spam are coming from.
Thank you. I am going to follow up with your advice.

If you need help setting up an anti spam, let me know. I'll be glad to help

Install Akismet and delete all previously approved spam comments.. Akismet would help you filter comments on your site.

Also block your site from allowing link comments.

Akismet is all you need, install it and set it up properly and that's all
