Currently we are dealing with company messages by using a function which return true or false based on number we send to that function, but as we know we need to block loot of users so instead of adding these numbers to that function we should have a string in which we append these numbers, and next time these numbers will be marked as company messages and ignored.

• String can be editable from orange-pi.
• String should be in SPIFFS.
