To be fair, Gill is bona fide, with a large portfolio of names I'd be delighted to get hold of.
One thing I've been curious about holiday.co.uk and holiday.uk is why those are the only domains in Domainlore's finalised sales list that has the actual price of the sale redacted. I suppose someone has asked for privacy to support any future transactions on those domains.
With regard to the OP, I prefer to take people as they come unless they cause me a problem. They haven't done anything egregious so I think, new or not, they deserve goodwill. Maybe I'm just soft and sentimental.
