I have a suggestion for the Rent24 team or the OP. You have to take care of this thread because is flooded with spam. There are only 4 pages so this is the beginning and there is still time to adjust and tweak things.
I see that you are running a bounty campaign where you ask members to comment in this thread. I think you should change the requirements for this task to avoid spam and abuse. Just add that post has to be 150 letters long minimum, on topic and that stakes will be paid after manual confirmation.
If this continues and there will be no reaction to this high amounts of spam I am sure that mods will clean this thread and put on the watch list to finally delete it in the end. This is a shame because you can have a high-quality ANN thread, just change requirements and actively moderate your thread.
Report all spam by yourself to avoid thread deletion.
I was thinking the same when I read the comments on page 1 of this thread.
In order to avoid useless spam comments here, the rent24 team could think about changing the task. For example, in stead of leaving random comments on this ANN thread to get free PRY tokens, the participants in the Primary Airdrop can be asked to answer a simple question. The answer to this question could be hidden in the Primary Whitepaper. Therefore, the participants will make an effort and at least scan the Whitepaper in order to find the answer to the question. This is a common practice in bounty/airdrop tasks.
