This coming from someone who never answers directly any challenges from anyone on this thread and words every response with personal anecdotes that can not be verified and juvenile name calling.
Using that logic all absentee ballots from people who voted for Trump whose total amount you do not know should have been discarded as well but you don't argue that. You of courser ignore it.
The signature verification was not immediately tossed away in the trash and this is why you again throw out an allegation as if its fact with zero proof and no that is not an answer and you again have provided zero objective evidence for your allegations-zero.
Finally in regards to how ballots are verified I would suggest you coming on this board and making unverified allegations does not pass any sense of credibility and unlike you I provide sources for how its done:
Whether a state requires voters to request an absentee ballot or participates in universal mail-in voting, all ballots cast by mail or dropped off at a drop box are vetted to ensure their legitimacy.

The mail-in voting process has several built-in safeguards that together make it hard for one person to vote fraudulently, and even more difficult to commit voter fraud on a scale capable of swinging election outcomes.

Now when you make an allegation of false ballots-you not me or anyone else on the forum must prove it. We are not hear to serve you and the onus is on you making the claim not me or anyone to prove it.
This sense of entitlement you have that people must prove your unsubstantiated allegations false is delusional.
