For my bachelor thesis in theoretical CS I paid someone to
- fix some weird LaTeX issues I had
- make some figures in LaTeX for which I provided exact (!) hand-drawn pictures
- adjust the document class/template (font size, margins, ...) to university standards
In particular, all the text, formulae, figure sketches and remaining, say, 70% of the remaining typesetting were done by. Let me also say that I got the best grade possible to highlight that my contents were more than substantial for a bachelor thesis.
By academic standards, is it ethical to outsource parts of typesetting one's (BSc|MSc|PhD) thesis by paying someone?
Note that I am looking for opinions about the academic culture, not about legal situations. My university regulations are especially blurry and demand that one's thesis must be solely produced (in German: angefertigt) by the author. Whether that includes typesetting and in what proportion, is probably up to interpretation.
