 and applications are not required to check for duplicate individual public keys.
 In fact, applications are recommended to omit checks for duplicate individual public keys in order to simplify error handling.
 Moreover, it is often impossible to tell at key aggregation which signer is to blame for the duplicate, i.e., which signer came up with an individual public key honestly and which disruptive signer copied it.
-In contrast, MuSig2 is designed to identify disruptive signers at signing time (see [[#identifiying-disruptive-signers|Identifiying Disruptive Signers]]).
+In contrast, MuSig2 is designed to identify disruptive signers at signing time (see [[#identifying-disruptive-signers|Identifying Disruptive Signers]]).
 
 While the algorithms in this proposal are able to handle duplicate individual public keys, there are scenarios where applications may choose to abort when encountering duplicates.
 For example, we can imagine a scenario where a single entity creates a MuSig2 setup with multiple signing devices.
