Members will start begging from them. With time, when the current members ( non merit sources) have expired all their Smerits, the it will be quite easy to spot merit sources. It would be interesting to see if some more changes are done in future to keep their identities hidden. More like given some additional Smerits to regular members based on their activitiy. The new system is still in its initial stages and thus it is very hard to predict the future. The admin has already stated in the official thread that necessary changes (like demerits)can be easily implemented along with merits.
