 From my point 'uncontrolled' means: no captcha or no per-IP time 
limitation - both of them leads to the ability for massive unlimited 
registration by automated software (bots).
By the way, I've found out that even time limitation doesn't provide a 
good protection from massive registrations: there is a malware which 
traverses the list of public server and registers one account per an 
iteration on each server in the list. The problem will become more acute 
when there will be hundreds of thousands of public servers available in 
the list.
