RE: cleaning up voting list.
There are legitimate reasons for removing names from these lists - death and moving into another state/county. I see no reason why this should not be a reasonable "housekeeping" matter.
For sure, some cleanups are legit. I think suppression came up in Georgia because it was done overzealously and in a way that worked selectively against minority voters who just didn't vote in every election. And, IIRC, some we're not notified they had been scrubbed, for "inactivity," but were still in the state, and seeing an election they DID want to vote in, were finding themselves to be unregistered at the last moment.
