I am not sure but I think one can not create two flag against same user in 6 months or something.
Yes, you are correct. Users can create flag on same user once in a 180 days period. But someone else with linking archived proof by creating a thread can create a new flag type if anyone feels the necessity.
These limits are in place:
- Per 180 days, you can only give 1 flag of each type to a given user. So you can't give someone multiple written-contract-violation flags in 180 days, for example.
- Globally, per year you can only create 1 flag per activity point you have, but at least 1/year.
