I found few more possible alt accounts of the OP by using his/her other twitter profile "https://twitter.com/seunyon" and this facebook profile "https://web.facebook.com/marsyayuannisa16" .

Both kokohpandan and Tunanetral are participant of [BOUNTY IS OVER][NEW NEW NEW] ROCKZ

I bet that I can still find more alt account by using kokohpandan's another Facebook profile "https://www.facebook.com/cokroalif16"

I wonder how many accounts OP has.

edit:
Another alt account (using "https://twitter.com/cokroalif16")
