Now more than ever it is against your best interests to tip on any automated platform. The data collected will definitely be used against you in algorithmic pricing.
These days it pays to aggressively demonstrate that you are price sensitive and will delay or cancel transactions at the slightest whiff of additional expense.
I only ever tip off-platform or cash even if I pay with card. Also that helps to enable my gift to go only to the service provider. It fucks me on some platforms but I find that an acceptable cost to not get algorithmically spitroasted. Besides, it also helps to eliminate predatory platforms from my ecosystem.
