Notes:
Someone suggested signing NOT+ENCOURAGE to mean "discouraged"

That raises the question:
Is "not encourage" the same thing as "discouraged?"
I would suggest that those are related but separate concepts.
You did great by sharing the link -- I'll just suggest that these are three different things:
1. don't encourage / not encourage
2. discourage
3. discouraged

The spreadthesign version showed the first meaning (above).

Meaning #2 will need a bit of expansion: "IX-(that person) SUGGEST YOU NOT (fs)-DO-IT! (Or some other discouraging statement)

Meaning #3 will use one of several approaches that indicate discouragement has occurred. The exact sign or combination of signs will depend on the type of discouragement being felt or experienced.

For example, suppose the feeling is along the lines of intimidation check out this version of that sign:
