Regarding this question posed by the BBC to "Orange Mike":

One of the people whose pages he [Cross] has been editing, and has edited over 1800 times, is George Galloway, and he says he knows that Philip Cross is being paid to do this. Do you think that’s likely?

People being paid to edit Wikipedia articles is not conjecture. It's an ugly truth about the platform. On rare occasions paid edits are investigated and exposed (https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2...) but more often than not Wikipedians fail to acknowledge that paid edits are even a problem. And that is itself a huge problem. If the patient can't even admit he's riddled with disease, what hope is there for successful treatment?

Personally speaking: I find it extremely hard to trust any article about celebrities, movies, politicians, products currently available in the marketplace, and even some foundational science and technology articles. It's so easy for paid PR to insert spin into these articles, or, as Cross has done, smears against selected targets.
