How can you say that my support requests haven't been ignored? Would you prefer me to re-phrase it as 'gone unanswered'?
Yes I would prefer you make that phrase instead, as it doesn't make an accusation against people.
A support page from many people filled with 'unanswered' support requests is being ignored by the developer.
That can be your opinion but unless the developers say this you will never know the reason why your support requests have been unanswered, and unanswered by the community.
You suggest I take action to 'avoid publicising it' – why on earth should it not be made public?
First discuss it with the plugin author, then once its fixed you can write a blog post about it if you want.
The status of 'volunteer' does not change these facts. Are you suggesting that people develop plugins out of altruism? Furthermore one of the 'volunteers' is listed as Disqus itself.
Yes people develop plugins out of the goodness of their heart all the time. Everything on WordPress.org is free, it's free to access and download, and to retrieve support from. To have a disagreement on that would suggest that you have paid for something from Disqus and are expecting some level of support from it. If so, please note that these forums are not the right place to hold commercial support. Commercial support should be discussed with the plugin authors/ developers on their own private support channel, as WordPress.org forums are volunteer-based. It is just unrealistic to hold those commercial expectations to a non-paid support forum.
It may well be discouraging to receive a negative review but I wholeheartedly stand by it. If the plugin authors wish to challenge any point I've made then they're free to do so – I believe my review is a fair response to the level of support I've received.
In that case we should let other people who are going to look at this know that you only waited 23 hours for support. Again, that might not be the right level of support if you are paying for something, but for something you've received for free expecting that level of support is unrealistic.
