Might I suggest to all e-juice vendors of the world to adopt a universal symbol that they can label their bottles with to warn people that the contents contain ingredients that are harmful to a plastic tank? Little stickers with these symbols on them would cost next to nothing and would provide customers with much more insurance that the products can be safely used in the appropriate hardware.

This example may not be appropriate (not sure if this is the symbol for plastic or for recyclable plastic), but a slash through the letters PC (for polycarbonate) would also work.
