Q, Q+, specifically the drops they author, here on this site only.
The person(s) that make up Q, as well as Q+, which is Q and team with @POTUS present, posts here, and on every platform you can think of. So that's twitter, insta, fb, etc. Each of the people in the administration do things to letter of the law. So, for example, Dan Scavino has 2 twitters. His official WH Scavino twitter, and his personal Scavino account. One he can post what is allowed within the law of being in a politically affiliated position in Gov't. The other, he can post whatever fuck-all he chooses.
