I used to be an enthusiastic gandi customer. No more. I'm pretty sure they've sold my query data, which has caused me no end of headaches and inflated my name purchasing costs.
Just a suspicion. I've bought many many domains over the years. Recently I've searched for highly niche domains I and seen them get snapped up and relisted by aggregators not long after I searched for them.
Also they definitely up the price if you search for a domain with it's suffix. I should have transitioned awhile back, it's on my todo list for this year.
