There was a discussion of this over at Hyperscale's forum yesterday, and it appears that there is a lot of confusion about this.
It looks like it's a badly-worded ad for their most premium of premium services.
If we go to PB's current pricing list, at
http://photobucket.com/pricing, we see that their current offerings are:
"Choose the plan that’s right for you and enjoy the premium member benefits.
Plus 50 offers 50GB of Storage and No Linking or 3rd Party Hosting - Get FREE monthly Print Shop giveaways & exclusive offers, valued up to $500
Plus 100 offers 100GB of Storage, Unlimited Linking and No 3rd Party Hosting - Two months free with an Annualized Plan
Plus 500 offers 500GB of Storage, Unlimited Linking and 3rd Party Hosting* - Plus 500 members receive all of the above, PLUS dedicated url and support
Ad free browsing"
Plus 500 is $39.99 a month, or $399.99 a year, billed annually. Plus 50 is the plan I have, with 50 gig of storage space.
It was also suggested in the discussion at Hyperscale that this could be a phishing scheme. For one thing, there are irregularities in the text that suggest it was written by someone whose first language is not English. For another, not everyone got the email.
In any case, as in all of the controversies regarding Photobucket over the past year or so, I haven't had any problems, myself, with accessing my account or linking images. I have had problems with images linked to Photobucket, when I access forums from work, because our web filter detects all of PB's popup ads and restricts the access. The symptoms in that case are that images take much longer to load, or they never load at all.
Prost!
