The question of whether or not to stop using Telegram altogether is a difficult one. On the one hand, Telegram does not provide an option to disable stranger PMs, which can be a security risk. On the other hand, Discord does offer this option, which can be a great way to protect yourself from scammers. Ultimately, it is up to each individual to decide what is best for them. If you are concerned about scammers, then switching to Discord may be the best option. However, if you are comfortable with the security of Telegram, then you may not need to switch. The Kukai team will never DM you, so if you do receive a random message, it is likely a scammer and you should block and ignore them. Additionally, the Kukai team may add a Discord in the future, so it is important to be careful and read the pinned message. Ultimately, it is up to each individual to decide what is best for them.
