If a user is wearing a paid signature a service, should readers view them as either personal endorsements about the nature of the service?

What is your opinion?

My opinion:
The advertisement should be considered as a paid advertisement, not a personal endorsement from the wearer.
However, users should be responsible for ensuring that the signature they are wearing is not a scam.
Similarly, readers should do their own research & due diligence before using any service, including ones within paid advertisements/signatures.
