This was in the latest release of 3.51 M33-6 readme:
"We've known that on some english-talk forums, there is someone called "McDanny" telling that he is part of M33 Team. This note is to say that he is NOT from M33, and just a faker wanting some attention. Please don't believehim, as you won't see any mail, notice or anything outside our webpage (m-33.narod.ru) or pspx forum posts."
"To the attention of becus25 and test30: Please do not do any of your releases based from our firmwares. You steal and change name but contribute a tiny 20-line plugin.You are a shame for psp development!"
"For not russian users - especially website admins:
For every sites, if you apreaciate our releases and the visitors that they bring to you,we would appreciate if you could put our paypal link in evidence as we need to purchase hardware matterials. Thank you."
I just wanted to state this in it's own topic, please respect these guys, becus25 and test30. I do not want them to stop making custom firmwares.
