Some of these are pretty interesting though. For instance, "avoid using repeated question marks". How is this a problem?
Well you can pretty easily turn something as harmless as a comment into something that absorbs the next line of code. Good luck debugging that one.

I've been programming C for 3 decades+ and that would have so bitten me, I had no idea about that. Luckily I avoid double question marks in code comments anyway (question marks in comment are more like mental notes to yourself during the phase where you try to make sense of some codebase, if things work out they should disappear anyway).
