If you flag it, you are helping the snake stay in its current unsatisfactory home. That you are worried and want to help says good things about you, but you can't take on the future of every critter on CL. If you every see an emergency situation, or downright intentional cruelty, yeah, then step in.
One thing you might think of, if you have energy and time, is to present to this site an idea for a new forum, 'The CL Revue' where people could link or describe these very kinds of ads. Perhaps such a forum could be arranged where the state would be mentioned first in the title. That way, those who had time and were ready for a challenge, and/or to do a good deed or random act of kindness, could look over the current CL disasters-in-waiting listed in the forum. With someone here, the hapless reptiles ready to be sold might have a little bit better of a chance at a good future.
