You will be giving the seller (who you don't know from Adam) your name and home or work address. The seller could use this information to identify you. Be very very careful. If you really want to buy online get a PO Box under a fake name
Say I had something to lose, reputation, wotnot. But only had payment methods that linked to my real name.
The seller would know who I was... think EU privacy legislation which is still active would make mincemeat of any seller (or employee of seller) that shared my personal info with hostiles, no ?. And could even make my daydream of a small, but not too small, lottery come true. But with compo. instead of numbers guessed right ?
If the seller/employee was more focused on profit/wage rather than their TRA mates' vendettas, yet I am still a cautious person. If entirely hypothetically I ordered stickers. Went to a loo. Closed the door. Stuck a sticker on the back of the door. Left. I could be seen on CCTV at some point. But not in the act of subversive stickering.
I guess the police if desperate to prosecute could use the fly posting legislation, do CSI things, trace the sticker back to the print shop, strongarm the print shop to produce the right invoice, match the names of both person in the CCTV film and person on invoice and celebrate taking me down.
But nothing is 100% guaranteed safe.
Doing nothing certainly isn't.
Overall, I think while there may be small risks, if you have to pay with a named credit card, and I would have to, the risks could be reduced to really tiny with a little creative thinking.
Hypothetically of course.
