Re: Large number of spammer registrations
You are right, I have to delete 15-25 spam registrations daily. Very much annoying. No harm done at my wiki, as I have to validate every user before he is able to create any page or post any message, but still, a daily pain. Not to mention that while deleting them, I may accidentally delete a valid user.
Only way I have thought in order to combat them is: add a tracker field in which they will have to write a specific word in my native language (my wiki is not english). Most of them (all perhaps) will not understand how to do that or they will not bother to install the specific keyboard. But: Is there a way, that if the field is not completed the way I want, then the user will not be able to complete registration? I don't know if this is doable.
And of course, this doesn't work for the english wikis...
