Can Someone Tell If I Ve Blocked Them On Snapchat?

When you block another person on Snapchat, they will no longer appear in your feed or in your search results. This indicates that even their conversation will be deleted. If you browse through your conversations page, you will see that there is no evidence of the individual at all. There is no sign of them whatsoever. On the other hand, the individual who is banned is completely unaware of this fact.
