I have found that a lot of spam trafic is coming to the site via search engines where people have used the search term "inurl:/blogs/home/"
I belive that if we or boonex could change the URL to the blogs that this would stop a lot of chinease spammers finding our dolphin based sites and joining up.
I have taken all the steps to stop these people signing up and joining my site such as turning on the confirm email on join, I have also turned all major modules like blogs, stores, events, ads, groups ect ect to dissalow imediat aproval, I block Ip's using the built in dolphin block ip system aswel as the cPanel ip blacklist on a daily basis.
However I find myself blocking IP ranges on a daily basis as well as re deleting the same users on a daily basis.
I strongly belive after looking at my site stats that if boonex or us can find a fix so as our dolphin sites are not listed in google when the term "inurl:/blogs/home/" is used this would stop nearly all of the chinease spammers being able to find our sites.
If you go to google now and type in inurl:/blogs/home/ and hit the button to search you will see that almost every link in the results are dolphin bassed sites (this is not good)
This is a screen cap of the stats for just oct 2011 from my site in blue is visitors using the search term "inurl:/blogs/home/"
