I know it may be added as a security measure like scam or buy-sell accounts, etc. But when a person sees that message, he or she may get a bad impression of the account. He or she may not trust the person, or the account may not get much interaction. Because I chanced password, now I'm tagged with that message.
This is a wrong perception. A notification of password recently change doesn’t give bad impressions. It’s just a security purposes to notify you and other member that you change password recently. Changing password regularly is a safe practice to protect your account given that you will remember all the changes.
The only time this action will be a bad impression is when you do a shady activity such as asking for loan or anything that involved money here since this will cause suspicion that your account is compromised.
