Greetings,
The maths captia is a good idea, but botts would quickly learn the
permutations if left in a standard format.
However, say as an example the question is framed in one of the ways below,
plus others of which I as yet have not thought:
3+15=
Three plus fifteen equals
3 +15 =
3+ 15 =
"3" + 15 "="
. . .
we can understand what is required, allowance needs be made to accept
eighteen or 18, within and no quotes.
Further, the site can pick up from whence the person is sending - i.e the
States, Russia, U.K, France, Nigeria . . . then perhaps the captia could be
questions the sender might be expected to know relating to the country from
which they are sending.
I am trying to think of something a UK citizen, or a UK visitor would be
expected to know it is far more difficult than I thought!
Sure you get the idea.
