I haven't deleted any, but I've kept a few so that I can make sure they are blocked.

I don't delete contacts. Once you're in, you stay in until the end of time. Got a family member's phone some years back, their contacts were added as well. I'll never call any of them, but their numbers will exist even when they no longer do.
The eternal agenda cares not for the living or the dead.

The last few died.

Trump supporters that were friends/family of mine are dead to me like Juanito. Don’t need that derangement in my life. Nothing admirable about Trump. A lot of contracts were deleted. Fuk em

Earlier this summer. I was cleaning my whole contact list out, removing duplicates, using it to remember folks I would like to catch up with. I've managed to keep my contacts list migrating from my first Nokia brick phone I shared with siblings about 20 years ago, so it was full of a lot of crap.

"Ginger, really good at math" is one contact I deleted. Was it Ginger the name or ginger the hair color? Was it a classmate or someone who was killer at splitting up a restaurant party bill? Idk, I have no recollection so out they go. So does "Stay Away from Steve" and "Another Mike, red ball cap" and "Good dancer Jess". "Shouty Shorty" remains because she's still my friend who is short and very loud.

The only number I remember removing is one that someone apparently stopped using and it was taken over by a spammer. Otherwise I leave it to know who is calling.

I removed my landlord right after I moved out of that lunatic's house.

Because they were names I’d been scrolling by for years and will never, ever intentionally call them. Nothing bad, just things like old work contacts, or even people from college and high school that were added decades ago and never left my phonebook.

I never wanted to delete them just in case one day I needed to get in touch with them, but it ended up turning into a digital junk pile that I need to clean out now and then.

I can always add them back in if we ever cross paths in the future.

I keep them because it's a resource. I can ignore a call if I need to.

Couple weeks back. I moved countries a few years ago and those people I haven't spoke to in a decade before that so no point on keeping them.

toxic old boss from before i got my professional job.
