I came across a thread that had a post by the user
Velkro, and I was surprised when I saw that his signature was missing. This user has been wearing a fake Bitcoin vanity address generator for years, but now it's gone.
I initially thought that he was banned because his last post was back in February, but BPIP shows no records that he was perma banned. It's possible he took it off himself, but somehow I doubt it. And why would he after such a long time?
I know that the admins don't moderate scams, but signatures by spammers (spamming signature campaigns) have been banned in the past. Did the admins finally make an exception and blocked his signature?
