It can be frustrating to see a community that you were once a part of or that you valued deteriorate in this way. It's understandable to feel disillusioned and want to leave the community as a result. However, it's also important to consider whether there are ways to try to improve the situation and bring the community back to its former glory. Here are a few things that you could try:

Try to engage with and encourage productive discussions: If you see a thread or conversation that is going in a productive direction, try to participate and encourage others to do the same. This can help to shift the focus of the community back towards meaningful conversations.

Report spam and misinformation: If you see posts or comments that are spammy or spreading misinformation, consider reporting them to the moderators. This can help to keep the community cleaner and more focused on accurate and useful information.

Reach out to the moderators: If you have concerns about the direction of the community, you could try reaching out to the moderators to see if there is anything that they can do to address the issues that you are seeing. They may be able to take steps to address the problem, such as banning disruptive users or tightening up the rules for the community.

Consider starting a new community: If the current community seems beyond saving, you might consider starting a new community that is focused on the topics that you are interested in. This can be a lot of work, but it can also be a rewarding way to create a space that is more in line with your vision for what a community should be.

I hope these suggestions are helpful. It can be difficult to see a community that you care about deteriorate, but there are steps that you can take to try to improve the situation and create a more positive and productive environment.
