Sorry, I'm not sure I understand - are you trying to get better SEO by making spammers look like valid authors?
That would just be plain Awful, Wrong, and REALLY EVIL™ I am sure that's not what the OP had in-
Yes. You are right.
*Drinks much more coffee*
In my view, these are not spammers. I think, as I read somewhere, these are the automatic subscriptions generated by some servers, or some software from a number of servers.
Nope, sorry but they are spammers and they lack any redeeming value whatsoever. You want to engage actual readers who are people and not "automatic subscriptions generated by some servers".
Don't ever attempt to validate spammers as legitimate. Akismet ships with WordPress because SPAM (and spammers) are the worst of the worst. There are other anti-spam plugins and you can and should use them.
Believe it or not, this has something to do with the automated work done in the background by the WordPress itself, just to increase the traffic of any site built using WP.
No. It really doesn't. Honest.
Any site that does that deserves to get hit with the Search Engine HAMMER of DOOM! and no one should visit those sites or any site that encourages that awful behavior.
Any site that attempts to validate SPAMMERS and somehow use them deserves the same fate. Spam is a problem and trying to justify or insist that they have some legitimacy is wrong.
However, I may be wrong. I love WordPress and never ever try to put any allegations on it.
I'm glad to read that. You're wrong by the way. ;)
Look spam is and always will be a problem as long as there are people trying to sell anything on the Internet. That can be products, people's email addresses, or they sell "clicks" to links.
There are ways to combat SPAM hitting WordPress and those are well documented.
But attempting to somehow turn spammers into something useful? No. Really, that has zero value and is just an amazingly bad idea.
