I have seen it happen on three venues, where catch reports have bought the circus to town. On two of those venues the fish took an almighty hammering.
On the third venue, a club took over, and managed to stop the same thing from happening.
I was a member of the first two venues, and along with other members warned them what would happen if they let the circus become members, they didn't listen. The fact that a member had also broken club rules regarding the publication of catches, also fell on deaf ears.
The third venue was a day ticket water, that hardly anyone fished, until someone reported their catch, plus all the facts about the venue.
I will also add, that when I had that Roach, it was the controlling club that gave the go ahead for it to be published, and a record claim. Had they said I couldn't, then I wouldn't have. Thats the reason I went to the club first before anything else. The venue and where the fish came from wasn't named.
I don't bother with catch reports, or venues reports. I find it far more satisfying working it out for myself, knowing I have done it off my own back.
