Before the changes I made recently, the maximum expiry you could have was 12 hours, which some people thought was too short, hence I bumped it up to 7 days.

One way is to decrease the maximum expiry for guests and allow people to sign up to gain access to longer expiries, which keeps the words in use down.

Otherwise, I can add more adjectives to increase the number of possibilities. There's already an adjective layer when the single word is exhausted.

Lots of ways to increase the amount of available permutations. for example, adding colors to the names (bluerose, pinkrose...) then even changing the position (roseblue, rosepink...).

Should be a solvable issue unless he gets really really popular.

Numbers or compound words?
