I actually disagree. I have made new accounts before (not for this reason) and had pleasant interactions with people who got upset at me before, many times. I didn't tell them because who cares, it wasn't anyone I actually knew or planned to get to know. The thing is that many people get upset or block over the most random little incidents, so it's often not that they dislike you as a person, but just because they made a snap judgement the first time. Nowadays I link my accounts, so this doesn't happen anymore, but it did happen super often in the past.
