One of the best ways that WordPress can improve is to add a reCAPTCHA option in comments. You would "turn on" reCAPTCHA by going to Settings -> Comments and checking a box "turn on reCAPTCHA". This would cut down on spammers a whole freakin ton.
The blog I need help with is deathgleaner.wordpress.com.
I believe that the only people who ever make this request may not putting their commenters' convenience first when they make this suggestion. In most cases it seems that those who make this suggestion don't want have to spend a few moments every day checking their Akismet spam filter for false positives.
I do not believe that adding CAPTCHA to wordpress.com free hosted blog comments would be an improvement.
What follows are my 6 reasons for respectfully dissenting with your opinion.
1. Many CAPTCHA codes cannot be read by people who are visually challenged as I am.
2. CAPTCHAs that use arithmetic questions are a barrier to people who have learning difficulties or cognitive disabilities.
3. The use of CAPTCHAs is NOT a barrier to unethical humans, who are paid to leaving spam comments and who re are becoming legion on the internet.
4. CAPTCHA are an annoying inconvenience to legitimate commenters who do not like being delayed by having to type in CAPTCHA codes or type in numerical solutions to arithmetic questions.
5. Many CAPTCHAs do not work as expected and the bloggers who have broken CAPTCHAs are not aware when they are broken, nor can the person trying to leave the comment tell them that the CAPTCHA is broken.
6. CAPTCHA's are not the best solution to prevent spam. Akismet is a superior choice and all wordpress.com blogs are already equipped with it.
CAPTCHA is seriously, seriously outdated technology. Wherever you're getting your ideas from, stop and get them from somewhere else.
Although captcha's do provide a primary level of defense against spambots, some of the more sophisticated bots are now able to read the more simple captcha's, and they are getting better all the time.
To get around things like like captcha and math comments, spammers are now paying people to make comments for them, and since they are "human" they simply enter the captcha or math answer and post their spam.
It's sad, but until something is actually done about spammers by the authorities, we will have to deal with this.
Thanks TSP
