I'd guess the time limit is so posters cannot keep changing the text hours or days later after others replied to it.
This looks like a rather large, distracting signature, compared to the few words posted. lol
"In order to keep signatures reasonable in size (to prevent them from overpowering the posts in a thread) the normally accepted criteria is that they should not be larger in total than 3 lines at normal (size 2) text size, or the equivalent (2 lines at size 3, 4 lines at size 1, etc.), including any spaces, etc.."

By all means let's be open-minded, but not so open-minded that our brains drop out.
