Ouch Whirlygig. That's a bit harsh.

There's nothing to stop PPLs hours building by cost-sharing, provided they comply with the law. The cost sharing provisions are in Article 130 (8) of the ANO.
Cost sharing is permitted as an exception to the normal rules about "valuable consideration" but there are conditions which apply if you are going to avail yourself of the exception.
Advertising in the manner you appear to have in mind is not permitted. However, restricted advertising is.
Hemac has already posted the provision relating to advertising.
It comes from Article 130 (8 ) (a) (ii) (cc):
"No information concerning the flight shall have been published or advertised prior to the commencement of the flight other than, in the case of an aircraft operated by a flying club, advertising wholly within the premises of such a flying club in which case all the persons carried on such a flight who are aged 18 years or over shall be members of that flying club."
People commonly believe that all occupants of the aircraft must pay their proportion of the cost. That isn't so. The pilot must pay at least his/her proportion. The balance can be divided between the passengers in any proportion they wish.
There is no requirement in the UK that passengers must be "close friends" or "close family members".

Do those words appear in the Danish law?
Privately owned aircraft:
The provision about the contribution to cost which may be accepted by owner-pilots is far more restrictive than that which applies to rented aircraft. There doesn't seem to be any logic in the distinction. I've always assumed it's because it would be too difficult to determine the actual cost per hour of flying the aircraft.
