Why do I get items removed for violating policy by having gel blasters with ammo, but others sell it

[coolcrapstore]

I have had to add a bunch of warnings and not include ammo with gel guns I sell.  But others sell ammo and gel guns with ammo and dont add all the warnings but they are allowed to do it?

There is a REPORT ITEM on every listing.  Right side, just above the item number.
