I totally agree.  I once had a dot.info, and it was the first WordPress Website that ever got spammed.  To the extent I had to pull it down.  I had to drop the domain completely.

I learned then that the name one chooses and the extension are very important to avoid being targeted for spamming.  Most of my domains these days are domain.net.  In future I'll try .com, as I've noticed .com is almost half the price than .net these days.  How times have changed!

Interesting ... I've only owned one .com domain till date, the one for my project that too, redirects to the .org (just registered to reserve our project name). I have  a .me for my portfolio, first year free from NameCheap and second year renewed myself. It's doing quite well, gets lots of visits and so do my other domains which aren't ".com"s. I've had WordPress too, and a blog until a year ago when I no longer had the time for it's maintenance, it was visited but never spammed as such. 

Thing is, all my domains are behind CloudFlare, till date there was only a flood attack on one of my domains, and CF's anti-DDoS feature served quite well to mitigate the attack in hours. I think you should consider this rather than sticking to ".com", well they are company domains afterall, even though they've become general purpose nowadays.
