public facing apology, long
The person I did this to, and those in the past I've done it to, likely will never see or read this, but I'm putting this out there because I feel like shit over doing what I just did. I'm also in a poor frame of mind and I should've done this first instead of making things worse.
I did something I've been trying to avoid doing and broke at least two of my own personal rules during and afterwards.
About 30-45 minutes ago, I replied to someone's post with unsolicited tech advice, without putting a content warning on it for being unsolicited (something I've promised to myself to always do) and not only that, came off as extremely condescending, which is the reason i try to not talk about tech too often or give advice to begin with. They then blocked me, which is understandable.
That's far from the worst of what I did.
Instead of posting an apology like this, I, in a lapse of judgement - although that in no way excuses what I did -, went around their block and sent an apology to one of their other accounts. This is also something that I've promised myself that I'd never do outside the context of personally being friends with the person, yet I did it anyway.
I've done this in the past as well with a handful of people, and I'm deeply sorry for doing this to everyone that I've done this to.
