In an effort to protect our users from abuse, we sometimes ask users to prove they’re not a robot before they're able to create or sign in to accounts. Having this additional confirmation via phone is an effective way to keep spammers from abusing our systems.
We want to make sure that this is really you and that you’re connecting to ThePiano.SG with just one account. Maintaining more than one account is a violation of the ThePiano.SG Terms. The only exception is a parent maintaining both his and his underage children's accounts.
