I'm a PhD student (very early on in my degree) in a relatively small lab. Over the last few months, I've spent a significant amount of time and effort designing my personal webpage to show my CV, publication preprints, etc. I tried to give it a unique style, and I'm proud of what I achieved.
Today I visited the personal website of a more senior PhD student in my same lab (same PI), and noticed that it was essentially a copy-and-paste recreation of my own website -- same HTML/CSS/JS, just with the name and details (publications etc) edited. My website is credited in an HTML comment, but few if any people will see this.
I feel a bit violated -- I never agreed to this, and there are lots of freely available templates for websites -- I don't know why this student had to use mine. I don't want visitors to think now that my website design is plaigarized from the other student's. That said, I don't want to sour my relationship with my labmates or PI or create conflict unnecessarily. Am I off base -- is this sort of thing acceptable in academic circles? How, if at all, should I navigate approaching this colleague?
