Systematic refusal on r/redditrequest submissions for very small communities

Hello ! Since a few years i have started moderating subreddits, especially small communities dedicated to bands or music festivals I'm into.

I believe i do a good job as i usually take the time to make a banner for desktop and mobile, I create a community icon, I make sure people trading tickets with each others through the subreddit can do it in the safest way possible, like with megathreads, I check reddit at least once a day to validate or sometimes remove submissions.

Yet I get systematic refusals for the last few requests I make on r/redditrequest, for communities that are restricted due to lack of moderator activity. If the sub still has mods, I always start by sending a modmail to the sub mod team to let them know the sub is restricted and should be opened again, but I usually get no answer.

The automatic bot reply doesn't give a clear explanation behind the refusals. So its hard for me to "improve" and do things better.

Is there any way to get some insight into the reasons behind these refusals ?
