Most people are senior in order to support their pay. They were hired on by another company cause they really needed someone and could afford them. That company's HR department said "there's no way I'm paying a junior web developer that, that's not what glassdoor.com says they should make". The hiring manager knew they'd be an asset worth "senior" status, because they knew they had to move quick and the candidate already had a week's worth of in-person interviews scheduled elsewhere. Thus, the web developer is now a "senior web developer". It's on their email signature, so you know it's legit.
