If they are evading their tax or other responsibilities then I certainly hope so. Why should I and other tax compliant citizens carry the can for others who engage in tax evasion (i.e. a genuine rip-off in Ireland in contrast to the so-called rip-offs that many people moan about)?
If they are evading tax then they should get into trouble - or at least settle their liabilities. This is not your problem. Of course if you want to facilitate possible tax evasion then that's a matter for yourself but nobody here would recommend it.
