@boris Well the developers' intent isn't the sole factor in determining toxicity. Sometimes things are just designed badly and result in unintentionally bad consequences.
There are good people who use bad software, and I will still defederate from instances of bad software run by good people, just like I defederate from instances of good software run by bad people. It is all about evaluating the consequences.
So when it comes to this particular bluesky bridge I will be evaluating it not based on there being good people on bluesky, nor on the professed character or intentions of the person who developed or runs the bridge. I will base my decisions on how the software works. If it is doing mass follow requests bases on an "opt out" policy, and if it is building up a massive PDS full of fedi posts to dump in the firehose that can enable bad actors to evade fedi blocks, then the bridge is blocked right away.
I will NOT wait for bad actors to take advantage of the toxic software before I block it.
