So, I like to set filters that automatically collapse certain posts that I may or may not have the mental bandwidth to engage with at any given time. Friendica lets me do this by regex, but some of them are kinda ugly

Take my Elon filter for instance. I could filter on /elon/i, but that would falsely trigger on common words like 'melon' or 'belong'. I finally settled on /^(.*[^a-z])?elon([^a-z].*)?$/i, but that feels overly complicated. Is there a better solution?

Edit: proofreading is for suckers.
