I don't know what things are illegal in this forum. So please tell me if I broke any rules.
I discovered that you don't lose merit when sending merit. I read how smerit works. To test it out I created aleph1 to dump all my smerit in and recovered half of it.
Bingoo! You do admit it's your alt account then.
Check this thread:
https://bitcointalk.org/index.php?topic=703657.0No you cannot lose your merits with any case but however you can loss your rank if you lose too much of your activity. So how can one lose your activity? If you delete your posts or any mods delete your posts (too much), that can cause the activity to fall down AFAIK.
