I think the forum is not the problem, the problem is imply if you meet the wrong hacker or hacker group.
I have been with HL since 2018, I already hired a hacker about last 5 months for phone hack which turn off positive after 9 hours. I will strongly suggest making enough research on any hacker you decide to hire from that forum.
Besides, Barrysanchez@ (hackermail) com was the same hacker I have been using for hacks since the past few months and I have never had any complains.
FYI always make sure you stay anonymous when dealing with these hackers just to be a safe slate.
