Bookwyrm627: How would that solve the problem? New accounts are easy and free to make.
erbello: Maybe it would not solve problem completely, but still, the Captcha on Register Page could decrease the speed of making spam a lot.
*shrug* That might help, or it might not. Some of the recent-ish spam has left me wondering if the spammer has some humans out there getting paid to post spam. A simple assembly line where one dude's entire job is to create new accounts could probably blow through the account creation process pretty quickly.
I (literally) don't know if it would do more harm than good.
idbeholdME: There are many possible ways that could stop or at least hamper the bots. Other forums have done it, so why not GOG?
"They did it, why can't you?" is a supremely unhelpful suggestion. :P
GOG has tried a few solutions over the years, some of which have done massively more harm than good.
