Does not require installation of any new plugins.

Tl;dr when registering, instead of a traditional captcha, users have to solve something like

Code: Select all

Q: Grass is to lawn as __________ is to forest.
A: tree
Apparently bots can beat easily Google-able answers, so keep that in mind. Implementation I've seen on other forums likes to give the user ample hints, since bots can't really use hints.

I'm not sure if it's case-sensitive, if it is that will suck.

Some questions people should be able to answer:

Code: Select all

Q: Which city is the Grand Exchange in? (Hint: Starts with a V, ends with a k)
A: _______

Q: What year does this project emulate? (Hint: Starts with a 2, ends with a 9)
A: _______

Q: Which F2P metal is better than Bronze but worse than Steel? (Hint: Starts with the letter "i")
A: _______

Q: When killing dragons, be sure to bring your "Anti-______ shield" (Hint: Starts with "d", ends with "n")
A: _______

Q: Casting the lowest level Magic spell requires Air runes and ____ runes (Hint: Starts with "m", ends with "d")
A: _______

Q: Burying bones gives you exp in the ______ skill (Hint: Starts with "P", ends with "r")
A: _______

Bad questions (the answer is Google-able):

Code: Select all

Q: How many coins does it cost to get through Al Kharid gate? (Hint: Less than 11)
A: _______

Q: What Prayer level do you need to use Protect Item?

I already have this set up friend.
It's temporarily disabled while I wait to make sure there are no more lingering spambot accounts from before the lockdown.
