So just to emphasise the 'old people attitude' to privacy, yesterday I legit edited out our living room sofa from the background of a photo of some ponies because it's our sofa and the internet doesn't need to see it. Literally nothing personal in the photo. Just not sharing the sofa. Nope.
In seriousness, you're right about data. I have resisted using facebook for stuff for so long for the reason that there's no security. I understand the issue of harassment and anonymous bullies online, but at the same time, I don't feel that safe posting in conversations as myself in case you accidentally get misunderstood. I won't pretend I haven't had that experience before :p. So yeah. I don't want to engage like that and it's a shame we're all expected to.
As for the off site image linkage, the old person me laughs at this a lot. Honestly. I mean, I remember taking photos with an actual physical camera, getting film processed at my expense and then scanning them into an ancient scanner...either for my ID site or for ebay. A lot of the time ponies got shoved in scanners, and they look like they are terrified by the experience. The whole idea of "omg, it's so difficult to find an external host and, like, link an image" makes me roll my eyes. This is why I don't think the brony fandom would last ten seconds in the 1990s/early 2000s trying to make a fandom work when the tech couldn't keep up.
I dug this up to show what I mean. This was my ID site way back in the late 1990s/early 2000s. Please ignore some of the information, as a lot of it was still being figured out. But the layout, intrusive ads, scanned pony images...a sample page link below. Most of the site does work but the main page is gone and some of the images have broken over time. Most of the non-scanner images were actual physical photos developed and scanned in to be uploaded.

...I am old. And proud of it.
