Yeah, at least probably. Started around 12, and one parent was tech savvy enough that he was likely all prepped to track and cut off access to things. Since I was a teenage boy, of course I did anything I could to get through the filters and shutoffs. A back and forth of shame, anger, challenging boundaries, shirking back in embarrassment happened. Groundings, talks, but over time, probably an implicit permission from my parents as long as I followed other said (don't stay up too late) or unsaid (don't use sketchy predatory chat rooms anymore) rules.
By 14 I was out and in a few-year long relationship so the computer was used less for anything porny. By 16 I had my own computer so they didn't interfere so much except maybe some lighter tracking (but doing little about it anymore) and shutting off the router when going to bed. By 18 I was out of the place so they didn't give a fuck anymore.
Because we were first on dial-up, and I had a nerdy imagination, much of what they'd have seen was links to fanfiction or erotica. Or evidence I was on those sketchy chat rooms. I was likely safest from parental tracking on ICQ/MSN or whatever those chat apps were.
I think my parents, or at the very least one of them, just wanted me safe above all else. And they were entirely right that I was being unsafe on those chat rooms, or otherwise talking to anons, and clicking in virus-filled sites (protection is much better and built into PCs today). They're not exactly gay-friendly, but they were very tolerant and wanted me to be okay. But they were not my birth parents, they were somewhat older than any birth parents likely would have been, and the generational gap between a socially liberal gay teen boy connecting to the new WWWeb, and (progressive?) conservative rural-centric baby boomer parentals that were relatively wary of technology, was just say too big for comfort and great communication. But I think we tried a little. When I got my boyfriend, maybe they just sighed in relief that there might be less tug of war over Internet access.
This was 00s. While overall acceptance of gay people has gone up even since (latest years have a more complex shift though), the 00s was very focused on attempting some form of acceptance for gay youth, so I was perhaps lucky there. There was no huge shaming over seeking gay porn (maybe underlying homophobia at worst), just protection of an early-teen, with much of it warranted, even if the talks with me were imperfect.
