There can be millions of liquid $openfund tokens hidden from @openfund users under the pretext of protecting users. And people may think, or it's ok, most of the tokens are in the hands of long term investors, so the price is gonna be stable and here comes some guy who did hide his liquid tokens by transferring to his alt account, so he stabs you in the back by dumping those tokens while you are sleeping.
Instead of hiding transferred tokens they can just put some notation like (transferred), so you can still see all of the tokens and tokens that user didn't buy are marked. They can easily do that. Ask yourself why they don't do it.
Openfund only shows users who have accepted the token ... the reason is that they don't want scammers to airdrop tokens to users to give an impression that the recipient has actually bought the token. Reasonable experience according to me.
