nope it's something I object to on ALL platforms.

It's usually used as a way to push things at you that you don't necessarily want but the platform owner wants you to see.

The very worst is doen by facebook who refuse to even give you the settings to switch it off.
Then there's amazon, who offer you 15 alternatives to something you've just bought - despite the fact you've just bought one.

Let people make up their own minds - unless, of course you ARE peddling paid for listings to the designers - in which case this is the means by which you push the paid for listinbgs over unpaid for listings.
