As with everything, we do endeavour to get things factually correct, and while you may not believe it, I/we do spend a lot of time trying to ensure the accuracy of what gets posted.
Occasionally, however, errors do occur - some bigger than others. Sometimes the writers get things wrong, sometimes I fail to spot them. It happens.
However, a somewhat pithy comment along the lines of "do your homework" or "sort it out" is not particularly appreciated. Let me ask; do you contribute to DiS in any way? Have you supported us through Patreon, or any of our other fundraising platforms? Because if errors are such an affront to you, then I suggest you give us the financial means to pay for some full-time editors, so such things do not harm your sensibilities in the future.
