This is a Python implementation of the private Yik Yak API.
It can easily be shadow banned because it does not mimic iOS device requests 100% (but it theoreitcally could) and it doesn't generate real-looking locations (but it theoretically could).
from yikyak import YikYakAPI
yyapi = YikYakAPI(None, 37.427367, -122.169982)
yyapi.registerUser()
messageID = yyapi.sendMessage('test').get('yakID', None)
for x in range (0, 140):
yyapi = YikYakAPI(None, 0, 0)
yyapi.registerUser()
print yyapi.likeMessage(messageID)
