Cerasus, I’m sorry but it’s not feasible to do as you suggest. The Crossword Solver site is free to users and, as such, we only have a small staff (ME) to look after the Admin side. Ash and his merry team of computer boffins deal with any technical issues.
I mostly manage to delete the spam but if there is a serious influx (Korean spam a couple of years ago when 100’s were being posted at one time) then Ash devices some means of preventing the spam reaching the Forum.
The trouble was that the measures taken to thwart the spammers had a knock on effect on users being unable to post.
Ash managed to sort this but it is a fine balancing act between thwarting and allowing bona fideusers to access the Forum.
If it gets any worse, then Ash is going to consider the next move, watch this space.
