azureus vuze 4 caution

[t-u-t]

i don't know what usually happens with this, but i have tried vuze 4  
on osx and reverted back immediately to 3 (glad i still had the  
installer) since it gave me the impression it is getting a bit  
intrusive.
first it auto-scanned for files, which seemed harmless, still would  
prefer it ask or explain first. but worst of all,
i got  those flashing "congratulations you are visitor 12345678"  
garbage right in my face.

can ppl give their opinion on this and maybe eventually leave version  
3 in ports in anycase
