Used to Work–doesn't now
It was never particularly good/professional, but I nonetheless bought this because it was a quick and easy solution for a problem I had. I've been relying on it for about 7 months, and only yesterday discovered that it has slowed to a screeching hault.
First: I just opened up one of my links randomly and noticed it took ~45 seconds to load. I went through the process of signing in with google. It works, but again..another ~45 second wait. I thought it must be a fluke, so I went and did the same with several other links–both custom branded and bost.link links. Same thing–and it was happening all day long yesterday, and it's still happening today.
I get email subs through them everyday. Only God knows how many I have lost. I have to assume only a small fraction are waiting around a full 1.5 minutes to subscribe to my newsletter. Can't believe I've been so stupid to trust this service.
Second: their homepage has been hijacked. It now forwards to a scam site, so all this stuff about them blaming their clients for the "malicious" site warnings is a bunch of bullocks. They aren't security-focused and who knows what their site is infected with. I don't know how long the site has been hijacked, but more than 1 day is plenty long for me to assume there's no one monitoring it.
