Gotta three issues to be addressed here:
One, I would like to know if I pay for License is it one time or do I have to renew every year? I have searched the forum, and read the License Agreement but couldn't find an answer to that.
Two, I am overjoyed by the Facebook (FB) sign in option. However upon trying it I came across one of those FB apps installation page. So suppose I install XenForo on my domain and enable FB logins, will the data collected from FB be stored in my server/domain or is it centrally collected at XenForo servers?
Three, How strong are Anti-SPAM defences in XF? Is it built to withstand X-rummer attacks? And all those porn-site promoters out there? I want a reliable forum that can be used by people I respect. It will be a shame if porn promoters ever take foot on my site. Show me all the key anti-SPAM measures so that I can evaluate them.
PS: XF looks amazing. I hope you guys (Xfrocks) are for the long run because it will be disheartening if you drop the ball down the road.
