I see where you are coming from but a blanket refusal is tough. People get into trouble for many different reasons. One of my clients was liquidated because the main contractor on a job he was involved in was liquidated owing him €240k. Is he to be refused the right to earn a living because this other company went into liquidation? Common sense must apply. The attitude of 'burn them burn them!!!' also results in many innocent people also suffering. The problem is how do we catch the deliberate defaulters.
When I say 'beware' I mean advisors and individuals must recognise that this is one possible outcome from a liquidation.
