Look, this whole thing is absurd like a Monty Python sketch, but much less funny.
Is this picture not safe for work..?
How about this one..?
And what about this photograph of an actual naked beaver I posted the other day..?
For me, all three could get me in trouble at work (because they clearly have nothing to do with the work I should be doing), and none of them would get me in trouble at the bus (though there's plenty of other pictures in Lemmy I wouldn't want to be caught watching in the bus to avoid embarrassing myself or others), but that's me, and that's why I don't use lemmy at work and if I use it on the bus I use a different account and only on communities I'm subscribed to.
But deciding whether to watch these pictures or risk watching others like them at work or the bus is my responsibility, not lemmy's, or the community moderators', or their posters'.
If I'm worried about “not suitable for work” I should be old enough to work, which means I should have a minimum of self control and be responsible for my own actions.
If I'm caught at work or on the bus with an “unsuitable” image on my phone because I was browsing some site that might contain images of that kind I'm not going to blame that site, or whoever posted that image, and I'm not going to demand of them to adapt to my particular circumstances and mark, censor, or remove any content I might find unsuitable.
That's my job, not theirs. They're not my fucking nanny, and I shouldn't need one.
Attempting to shift the blame for my own actions to the people providing me with this content (and for free, no less!) would be childish, petty, and disingenuous, to say the least.
