why in tax season there's suspicious new vendors everywhere

every year around tax season i notice random “brands” popping up on ig or telegram selling carts or thca. feels like people trying to cash in when refunds drop. some even copy legit packaging. browsing weknowflower, i’ve seen buyers post pics and receipts showing how inconsistent a lot of these newcomers are compared to what they claim. now my rule is simple if a vendor only shows up around refund time, i don’t touch them. anyone else notice this cycle?
