This is a very good catch and just thinking of it, I can see so many ways this "bug" can be exploited and used to scam or steal accounts. Would not post them, as not to give anyone ideas, but a certain tag should be added so hyperlinks would be distinguished from the rear of the post.
Also, would it be possible to have a notification before opening links, sort of "are you sure you want to b redirected to..."
This would prevent inadvertently clicking on links, especially when you're on mobile.
Adhoc links or hyper-text-links is one forum programming that I like. You know, it states the links subject simply and it can be easily used in a way that, it blends with the sentence structure although yeah, as proposed by OP, it could be used to do some damages. Scammers who are phishing for whatever details are fully aware that, one is likely not to click on a suspicious link and as such would just go for an alternative in making a harmful link seem harmless by making it click bate and forum related enough to make users loose therr gaurd. I once saw a user whom reported right here in meta of an attempt by some other user to pish for his login details using adhoc or hyper text links through a pm.
I don't see how this can easily be abused for phishing. That's much easier by using a fake visible link:
google.com.
I understand the scenario your trying to relate here, in relating to the fact that, the probability of users falling victim by clicking a hyper texted link within a wall of text is less than that of a link being simply stated out and that's true. That's really true but even at that, if we are to take a look at the operation of most ads these days, the 'x' and '>' symbols along with others have been known to skip the ads or pass and somehow, these guys have input that in there programming while the count down is still reading with the skip icon yet to be displayed. Where your attempt to skip ends up being you, clicking the redirecting page itself. Like, a whole page serving as a link. Same guys for the forum too. Some serious user might use his or her whole text as an adhoc link and your little attempt to keep your device brightness on by just clicking or taping your device screen, ends you in a redirecting pathway.
