This morning two different users posted a 6.0 version of this miner.
I noticed both posts got deleted so I guess they were spammers.
Sadly I downloaed and launched that 6.0 version.
During the day, a huge number of posts with suspicious links to download PhoenixMiner 6.0 are deleted. I personally nuke several dozen users who post such posts during the day.
Before downloading, read the first post of the topic. It also clearly states that:
Follow only the posts of the author of the topic and the changes in the first post. Only his posts contain clean download links.
