Remove email addresses from public pages

### Who
Could you please remove mail addresses from bounties? You can see my personal mail address if you scroll eg to the very bottom of [this github bounty](https://gitcoin.co/issue/aragon/aragon-monthly/284/1850)
I assume they're also still visible by google & other scrapers in other inactive bounties but can't seem to browse to these.

Mentioned this before in the townsquare (where someone responded) bcs I didn't want to get scraped. But can't find my own request with search :/ , so logging it here again.

Just was reminded of it bcs I found myself in a pastebin file via yougotpwnd, leading to... gitcoin. :/

thx & keep up the good work
