Irregardless is a non-word that many a tool mistakenly believe to be correct usage in formal style, when in fact it is used chiefly in nonstandard speech or uneducated writing. Coined in the United States in the early 20th century, it has met with a blizzard of condemnation for being an improper yoking of irrespective and regardless and for the logical absurdity of combining the negative ir- prefix and -less suffix in a single term. Although one might reasonably argue that it is no different from words with redundant affixes like debone and unravel, it has been considered a blunder for decades and will probably continue to be so.
To be honest, I dont mind people using words like this in normal speech, but I cant stand to see it in print. People like journalists and authors, I believe, have a responsibility to be at least somewhat gramatically correct.

Me: "Yes, and it's a sad testiment to the quality of education in society when these mistakes are sanctioned!"
