Receiver has a generic name

Reports receiver names like me, this, self, or names that differ from other receiver names for this type.

Example:

func (self *MeterSnapshot) Rate5() float64 { return math.Float64frombits(self.rate5) }

According to Receiver Names at github.com/golang, you should not use generic names such as "me", "this", or "self". These identifiers are typical for object-oriented languages and might give the method a special meaning.
