Hey jonesy here with 5 reasons on how to avoid fake furni
1. Only trade with friends you know don't fake?
2. Dont agree to unrealistic trades (ex. your deluxe for their tire chair)
3. You can not trade at all and only use flts and catalogue to get furni
4. Check their rooms, usually if they fake people will have made rooms about them saying... BLAHBLAH MAKES FAKES!!..so search their name and if you see names like that dont trade them. (duh)
The Last and final reason
5. Quit coke and dont come back until fake furni is patched (lol)
ask them to agree and cancel 5 times (they know it really doesnt make their furni disapear so usually they be glad to do it) then on like the 3rd or 4th time agree really quick and put down REALLY fast so that urs is real and theirs is a fake =D i dunno it worked for me 2 times now.
