⚠️ ⚠️ Important Unfortunate News⚠️ ⚠️
I was just contacted by Typeform that they had a data-breach and an unknown hacker downloaded all of the results from all Typeform forms prior to May 3rd, including the Sneepsnop Sign-Up form 
The good news is they didn't acquire anything else;;
That spreadsheet had your provided email address and Mastodon handle.
But! I have informed you!! I did my duty for sneepsnop and snoopsnort
next year i will look into alternate form builders
I'm guessing you're going to get spam and phishing emails because of this. I don't think anything in that spreadsheet could be used to hack your mastodon accounts and whatever bot downloaded and runs through the spreadsheet isn't gonna know what a mastodon handle is and will probably just try to add it to their email lists
