Now it's back on, security issues tightened, upgraded to DNN 8.0.4 and latest YAF. However I have two issues:

a)Avatars are still not syncing with user profiles (they didn't sync before either, but now I'd like to try and fix that)

b)Deleting the spam accounts in DNN did not result in their removal from YAF. I plan to run

select * from yaf_user where [Name] not in (Select Username FROM Users) and userID>1

and run yaf_user_delete from each one. Is this the correct approach? Do I need to take something else into consideration?

Did you see any issues in the YAF Event log?

Did you disabled hot linking on your server?

Technically if you upgraded yaf after you upgraded dnn then when you delete a user in dnn it also should delete it in YAF. But is possible that the process changed in dnn. Its possible the injected Stored Procedure doesnt work anymore.

yes if you do that manually that would be the correct way.

I'm seeing this:

Error while Syncing dnn userprofile with Yaf

And also this:

Also, not sure what you mean about hot linking? Is it a particular DNN or YAF option?
