Anonymously! But the benefit is that it doesn't send a notification to people following the thread, it just moves it up on the newest post page. I think it's a nice feature for trying to get some attention for older threads for lesser known models - better than empty comments or new threads anyway.
It's pretty annoying for really well known models that just aren't making content anymore, like the guy that bumps the Belle Delphine thread every day even though there hasn't been anything new in a year.
All in all, I think the bump is a good feature, but it would probably be better if it had some sort of cooldown attached to it, like not being able to bump a thread unless it's been inactive for 2 weeks.
Sure if there was a cooldown, it would at least make a little sense. But seeing all these threads that haven't been touched in forever while also at the top of the new section everyday is stupid. plain and simple. The Alerts section is already a dumpster fire, so I use the 'watched' page where it looks like every thread has been updated, when really it hasn't.
