Great thread. Thank you very much. One element you never mentioned is whether we should use our correct personal details or not. What do you recommend?
On one hand if you register a domain with your correct personal info then the domain it is probably yours forever. I usually give back 10% to 20% of all recreated domains just out of goodwill because former webmasters complain. Then when the transfer transpires your personal details are exposed. Also, when you buy expired domains using your personal details you have to pass on the best opportunities. For example, there have been multiple occasions where I passed on buying former government and institutional sites because I was paranoid about my personal details. You do not want to recreate the former .ca RCMP site using your real personal details. These opportunities come around quite frequently. So I miss out on the best opportunities when I use my real personal details.
On the other hand using fake personal details has disadvantages as well. More and more domain registrars are asking for more information like a copy of your credit card. Payment processing with VCC and fake paypal accounts is becoming more difficult. I just got a letter from a registrar the other day reminding me to update my private whois info because the TLD regulatory body has the right to seize the domain if they can prove I used fake details. They are getting more sophisticated and using fake personal details can turn into a clusterfuck of wasted time.
What do you experts recommend?
I've never faked my details with registrars, for me, it's always been too much effort.
I've got my sites split between a few different registrars, all in my name, but all with who.is protection.
I've also got accounts setup in my girlfriends name, I just transfer her the money I spend.
So every registrar account I am involved in is 100% legit and not faked.
Going a bit further into your comment, it's worth remembering that Google itself is a registrar:

I imagine that they have complete visibility on everything, so what domains have dropped/expired.
I'm not too paranoid about my details being out there to be honest when I've handed back a domain. I think if Google really wanted to hammer me, they could do it.
But despite them having all of this information, nothings ever happened. I even see competitors PBN's with massive footprints and no who.is protection and they're still ranking!
My logic is that Google have got bigger targets to worry about than my small network.
With regard to opportunities, I only buy .com's, .org's and .net's, so no country specifics like .co.uk or .ca that you can't mask.
I usually always pass on domains that could blow up on me, as you said, anything related to the government, charities or related to legal firms.
Can you image a pissed off lawyer coming after you for a domain? Fuck that!
I regularly check emails for my network and always have a contact form. Just like you, if someone wants the domain back, I just give it back!
