where is this setting - to add comments one must be logged in one of my blog is getting too much spam, some one is posting the same thing again and again, what is the easy way to stop that. looks like some kind of bot. Apprecite any help.
Forcing people to register before commenting will, in many cases, turn potential commentors away. Activate spam protection like Akismet instead.
Are you using wordpress? If you are, then you could use the http://www.captcha.net/ plugin. I use their captcha on my own blog website and I get almost no spam, (anymore), and that's for a few hundred blogs. FFMG
this is the corerct way..there check the correct option...... yes but when u ask people to register and get free gifts..then they don't go away..this way on registering enhances relation between users and the author...so i prefer that...
