lots of bad data feeded to fa

FlightAware ADS-B Flight Tracking

Last weeks i see a ton of bad data feeded, it seems fa removed some error checking, why?? (mostly speed errors)
My feed seemed to be ok most of the times i think untill VRS showed errors too today. as example flight VLG8539 on the top flying ssw, causing the 3 spikes was in fact south instead of far north of my antenna; at the time this screencap was taken it was at the border BE-FR. (acccording to fr24)
…the one to the NE was also new today…

but I also got almost an hr of flight in the log for this one, which isn’t bad at all 8)

fa should add (again) some error checking algorithms…

Where do you see the bad data?

If you are plotting with VRS then VRS is doing its own interpretation of the raw data; this is unrelated to what FA does with the data.
