Personally, I chose .space simply because it's cool, cheap, and not overcrowded. It also seems to lend itself well to being part of a name.
I know spam is a hard problem, but I wish you wouldn't label me a spammer simply because of the TLD I chose.
There are a few others which you may want to avoid according to this report: https://securityintelligence.com/enticing-clicks-with-spam/
> Why did you end up going with a .space domain? We blocked that whole TLD because we were getting massive amounts of spam from it when it first came out.
From your comment:

The author is not "labeling you a spammer". They're simply stating a fact about their experience. And in fact, it doesn't even mention you.
I only tried to hightlight that they have, in effect, labeled everyone in .space (not just me, but me included) as a spammer.
It's heavy handed, but I understand there are sometimes pressing needs for quick solutions, like when having your mailboxes flooded with SPAM. Hence, the "I know ..." clause.
