Ok, I am going to try and write this kindly and professionally. I have posted a million links on this subject. I am going to put this in nice plain writing.
1. About Page – Why would I comment with no photo or credentials listed on an about page?
2. Gravatar Image – Why would I click on a Gravatar that looks like a spam image?
Not going to…why? Too much spam. The Gravatar, should have your photo, along with your profile. This creates trust. Trust is essential.
Why would I trust to comment on your blog, with no “about page” and no Gravatar image? I will not. Gravatar image must have a photo. About page must have a photo with information about the author.
Look at a book…it has a photo of the author and credentials or information on the cover. Correct? Yes, it does. I will not visit your site or comment without a Gravatar or an about page. Why? Think you are a spammer. Why? No credentials.
I am having technical issues with my Gravatar at the moment. Contacting WP to fix this issue, as it is not showing correctly on other sites.
Noticed many spammers on WordPress lately, with crazy Gravatar images. I do not visit sites unless it is a real photo of a person.
Posted this, just to let readers know background information on spammers.
